5.  The applicants are Russian nationals who are close relatives of persons who disappeared after allegedly being arrested by servicemen. In each of the applications the events took place in areas under the full control of the Russian federal forces. 6.  The applicants complained to law-enforcement bodies and official investigations were opened. The proceedings were repeatedly suspended and resumed, and have remained pending for several years without achieving any tangible results. The investigations consisted mainly of the authorities making requests for information and formal requests to their counterparts in various parts of Chechnya and Ingushetia and other regions of the North Caucasus to take operational search measures. The requests received negative responses or no replies at all. 7.  From the documents submitted it appears that the relevant State authorities were unable to identify the State servicemen allegedly involved in the arrests or abductions. 8.  In their observations the Government did not challenge the allegations as presented by the applicants. At the same time, they stated that there was no evidence to prove beyond reasonable doubt that State agents had been involved in the abductions. 9.  Below are summaries of the facts relevant to each individual application. They are based on the statements provided by the applicants, their relatives and neighbours and copies of the contents of the criminal investigation files furnished by the Government. The personal data of the applicants and their disappeared relatives, and some other key facts, are summarized below and in the attached table (Appendix I). 10.  The applicants are:
(1)  Mr Gerikhan Sultygov, born in 1972;
(2)  Ms Fatima Sultygova, born in 1966;
(3)  Mr Musadi Samrailov, born in 1943, and
(4)  Ms Maus Nasayeva, born in 1953.
The first applicant resides in Chippis, Switzerland. The second applicant lives in Boras, Sweden. The fourth applicant resides in Grozny, Chechnya; prior to his death, the third applicant also lived there. 11.  The third applicant, Mr Musadi Samrailov, passed away on 3 February 2013. Mr Viskhan Samrailov, his grandson and the son of Mr Visadi Samrailov, expressed his wish to pursue the application. 12.  The first and second applicants are the siblings of Mr Alikhan Sultygov, who was born in 1969. The third and fourth applicants are the father and stepmother of Mr Visadi Samrailov, who was born in 1964. 13.  In 2000 the Sultygov family, including the first and second applicants and their children, moved from Grozny to Ingushetia owing to armed hostilities. In the summer of 2000 Mr Alikhan Sultygov returned to Grozny to check on the family house left behind. 14.  On the morning of 4 August 2000 Mr D.U. and Mr Alikhan Sultygov drove in the latter’s Volga car to the house of the Samrailov family through checkpoint no. 7 on the outskirts of Grozny. The checkpoint was manned by servicemen of Special Police Forces Unit (OMON) from the Sverdlovsk Region. The servicemen checked Mr Alikhan Sultygov’s and Mr D.U.’s identity documents and let them through. 15.  On the way back, after having picked up Mr Visadi Samrailov, the three men were stopped at the checkpoint and detained. Mr Alikhan Sultygov, Mr Visadi Samrailov and Mr D.U. were placed in a UAZ vehicle and taken to the Leninskiy district military commander’s office which was situated in the same building as the Leninskiy district department of the interior (the ROVD). Mr Alikhan Sultygov’s car was driven by one of the servicemen. At the office the three men were blindfolded, their hands were bound and they were put in an APC which took them to the main base of the federal military forces in Khankala. 16.  Upon their arrival at the base the three men were put into a pit measuring about two or three metres in depth and about one and a half metres in diameter. The bottom of the pit was covered with stones and broken glass. The three men were not allowed to remove the blindfolds and their hands remained bound; they were not fed, and only given water. The soldiers threw stones at them. 17.  On the next day several servicemen took Mr Alikhan Sultygov out of the pit. He never returned. Two days later the servicemen took away Mr Visadi Samrailov. Later on the same date Mr D.U. was also taken out of the pit, driven for about thirty minutes and released on a highway. The abductors told him to keep his blindfold on for thirty minutes and threatened to kill him if he shared any information about the detention. Then Mr D.U. walked to Grozny. 18.  The applicants have not seen their relatives Mr Alikhan Sultygov and Mr Visadi Samrailov since 4 August 2000. 19.  On an unspecified date in September 2000 the third applicant was questioned about the abduction. He informed the investigators about the details of the events, as related by Mr D.U., including the arrest at the checkpoint and subsequent detention in a pit in Khankala. 20.

In addition, she stated that along with her husband the servicemen had also arrested Mr Alikhan Sultygov and kept him in the pit and that the first and second applicants were searching for him. 21.  On 22 October 2004 the investigators questioned Mr Visadi Samrailov’s sister, Ms M.I., who stated that on 4 August 2000 an employee of the Leninskiy district military commander’s office, Ms Ya.Ya., had told her that Mr Visadi Samrailov had been brought over to their office and then taken to the military base in Khankala. 22.

In addition, she stated that on 4 August 2000 the district military commander had personally confirmed to her that her son had been brought to their office and detained there until 4 p.m. and then taken to Khankala. 23.  On the same date, 22 October 2004 the investigators also questioned the third applicant, whose detailed statement was similar to the ones given by Ms M.I. and Ms A.I. In addition, he stated that at the military base his son, Mr Alikhan Sultygov and Mr D.U. had been kept for several days in a pit and that he had learnt about the details of their detention from Mr D.U. 24.  On 25 October 2004 the investigators questioned Ms Ya.Ya., who stated that in 2000 she had worked at the Leninskiy district military commander’s office and that on an unspecified date in August 2000 she had seen, on the premises, Mr Visadi Samrailov, who had been standing in the hallway with his hands above his head against the wall. At the time the district military commander was officer S. Pe. 25.  On 10 November 2004 the investigators questioned Mr Alikhan Sultygov’s mother, Ms A.S., whose statement was similar to the one given by the third applicant. In addition, she stated that she had learnt the details of the arrest and the subsequent detention from Mr D.U. 26.  On 19 March 2007 Mr D.U. wrote to the investigators providing details of his arrest at the checkpoint and the subsequent detention in Khankala with the applicants’ relatives Mr Visadi Samrailov and Mr Alikhan Sultygov. This information was included in the case file; he was not questioned by the investigators.
(b)  The main investigative steps taken by the authorities 27.  On 7 August 2000 the third applicant was informed by Mr D.U. of the abduction of Mr Visadi Samrailov. From the documents submitted it follows that on an unspecified date prior to 13 September 2000 he complained about the abduction in writing to the Leninskiy district prosecutor’s office and the Leninskiy ROVD stating that his son had been detained at the checkpoint and then taken to the ROVD and the military commander’s office. 28.  At the end of August 2000 Mr Alikhan Sultygov’s mother, Ms A.S., received a note from Mr D.U. stating that her son had been arrested. She immediately went to speak with him; having learnt the details of the arrest and subsequent detention in the pit, she complained thereof to the Grozny military commander’s office. 29.  On 17 March 2001 the district prosecutor’s office opened criminal case no. 11094 to investigate the abduction of Mr Alikhan Sultygov and Mr Visadi Samrailov. 30.  On 17 March 2001 Mr Visadi Samrailov’s wife, Ms M.S., was granted victim status in the criminal case. 31.  On 17 May 2001 the investigation was suspended and on 5 June 2001 it was resumed. The applicants were not informed thereof. 32.  On 6 July 2001 the investigators examined the detainee registration log of the Leninskiy ROVD. According to entry no. 262, on 4 August 2000 Mr Visadi Samrailov had been taken to the ROVD and then handed over to colonel Korolev. 33.  On 13 August 2003 Mr Alikhan Sultygov’s mother, Ms A.S., wrote to the investigators describing the circumstances of her son’s arrest at the checkpoint, his transfer from the ROVD by colonel Korolev to the military base in Khankala and his subsequent detention with Mr D.U. 34.  On 10 November 2004 (in the documents submitted the date was also referred to as 7 August 2006) Ms A.S. was granted victim status in the criminal case. 35.  On 29 March 2007 the third applicant wrote to the investigators asking them to resume the proceedings. He also stated that Mr D.U., who had previously refused to give statements to the authorities out of fear for his life, had agreed to be questioned. 36.  Between 2001 and 2007 the investigation was suspended and resumed on several occasions. It was last suspended on 5 May 2007. The applicants were not informed thereof. 37.  From the documents submitted it follows that on various dates between 2001 and 2007 the applicants and their relatives sent numerous requests to various authorities asking for assistance and information on the search for their relatives. 38.  On 9 June 2007 the third applicant requested an update on the progress of the investigation. No reply was received. 39.  On 26 October 2009 the investigation was resumed. It is still pending. 40.  The applicant, Ms Fatima Bekova, was born in 1963 and lives in Nazran, Ingushetia. 41.  The applicant is the mother of Mr Ruslan Yandiyev, who was born in 1982. 42.  At the material time the applicant and her son, Mr Ruslan Yandiyev resided in a block of flats at 19 Moskovskaya Street in Nazran, Ingushetia. A block of flats was under construction nearby. 43.  On the morning of 29 September 2005 the applicant left for work. At about 9 a.m. on 29 September 2005 Mr Ruslan Yandiyev went to the construction site and met Mr M.-A.B., an acquaintance who worked there. After a while they were joined by Mr I.Kh., another worker from the site, who had arrived in his “Moskvitch” vehicle. The three men went to the workers’ trailer situated at the site. 44.  Shortly afterwards two vehicles arrived at the construction site: a silver VAZ-21099 vehicle with a registration number containing the digits “06” and a red VAZ-2107 vehicle with the registration number “586 mr 95”. A group of armed men in camouflage uniforms got out of the vehicles and broke into the trailer. Most of the armed men were of Slavic appearance and spoke unaccented Russian. Some others wore civilian clothing and spoke Ingush. 45.  Having broken into the trailer, the armed men immediately started beating Mr I.Kh. and dragged him outside. When Mr M.-A.B. and Mr Ruslan Yandiyev tried to intervene the armed men took them outside and forced them into their vehicles. They then put Mr I.Kh., unconscious and bleeding, into the boot of one of the vehicles and drove away with the three men. The abduction took place in the presence of several witnesses. 46.  The applicant has not had any news from her son, Mr Ruslan Yandiyev since that day.
(b)  Subsequent events 47.  On the following day, 30 September 2005, the applicant arrived at the construction site and learnt about the abduction. She immediately complained thereof to various law-enforcement authorities, including the Ministry of the Interior, the Federal Security Service (“the FSB”) and the Nazran town prosecutor. 48.  On 14 October 2005 a convoy of four white Gazel minivans, a UAZ minivan (“таблетка”) and some other vehicles, arrived at the construction site. A large group of representatives of law-enforcement agencies searched the site looking for hidden explosives and ammunition. Mr P.E. and Mr P.A., who had been present at the site on 29 September 2005, recognised some of the officers as the latter had participated in the abduction of Mr Ruslan Yandiyev. 49.  The Government submitted that on 14 October 2005 a large group of law-enforcement officers had searched the construction site looking for explosives and that on 29 September 2005 no special operations had been conducted to detain Mr Ruslan Yandiyev. 50.  On 9 October 2005 the investigators questioned the applicant, whose statement was similar to the one submitted to the Court. In particular, she stated that she had learnt from workers at the construction site that on 29 September 2005 a group of armed men speaking unaccented Russian had arrived at the site in two vehicles, had beaten Mr I.Kh., Mr M.-A.B. and her son up and taken them away. 51.  On 28 November 2005 the applicant informed the investigators that she had information concerning the possible identities of the police officers from the special forces unit who on 29 September 2005 had taken away her son and two other men from the construction site and on 14 October 2005 had returned to the site.

On 30 August 2006 the investigators questioned the senior investigator of the Directorate of the Federal Drug Control Service (“the FDCS”), Mr T.S., who submitted that in the autumn of 2005 he had received information concerning explosives hidden at the construction site. He had gone and inspected the site and the trailers with a number of other officers, including officer I.T. They had found nothing of interest. On that date the FDCS officers had used a UAZ-452 minivan (“таблетка”), an armoured Gazel minivan and a VAZ-2105 car. 54.  On 10 September 2006 the investigators questioned the deputy head of the FDCS, officer I.T., whose statement was similar to that of the senior investigator T.S. In addition, he stated that upon receiving information concerning hidden ammunition or explosives at the construction site, he had informed his superiors and the regional department of the Federal Security Service about it. Then he had gone to the site with Mr Ib.T., the senior investigator Mr T.S., an expert and officers from the special forces unit of the FDCS. At the site they had been joined by officers from the regional department of the Federal Security Service and the Ingushetia Ministry of the Interior. Nothing of interest had been found during the search and the law-enforcement officers had left the site. About a month later he had again searched the trailer and the site with a group of officers from the service and the police but had found nothing of interest. According to the witness, he had learnt of Mr Ruslan Yandiyev’s abduction at some point later. 55.

(b)   Main investigative steps taken by the authorities 70.  On 9 October 2005 the Nazran town prosecutor’s office instituted a criminal investigation into the abduction of Mr Ruslan Yandiyev, Mr M.‑A.B. and Mr I.Kh. The case file was given the number 05560115. 71.  On the same date, 9 October 2005, the applicant was granted victim status in the criminal case. 72.  On 1 December 2005 the investigators decided to follow up on the applicant’s information of 28 November 2005 concerning the perpetrators’ identities. 73.  On 15 September 2006 the investigators informed the applicant that the steps taken had not led to the identification of the perpetrators. 74.  On 15 September 2006 the Ingushetia prosecutor’s office, the supervisor of the investigators, informed the applicant that all possible steps to solve the crime had been taken. In particular, from the statements of the FDCS officers questioned by investigators it followed that on 14 October 2005 the officers had indeed inspected the trailer and the site but had not arrested the applicant’s son. 75.  On an unspecified date between October 2006 and February 2007 the investigation was resumed and then suspended again on 19 March 2007 76.  On 20 August 2007 the applicant was allowed to access the case file. 77.  The documents submitted show that on numerous occasions between October 2005 and August 2007 the applicant complained to various law‑enforcement agencies about her son’s abduction by officers of the Ministry of the Interior, stating that a number of witnesses could identify the abductors, requesting that the investigators take a number of urgent steps to solve the crime and asking to be kept abreast of the progress of the investigation. 78.  On 26 May 2008 the applicant complained to the head of the Nazran Town Department of the Interior that the night before two unidentified persons had threatened to blow her house up if she continued to persist with the investigation into her son’s abduction. 79.  On 1 July 2008 the FDCS informed the investigators that their internal inquiry had not confirmed that the three officers who, according to witness Ms F.A., had participated in the abduction on 29 September 2005 had actually been present at the construction site on that date. 80.  The investigation into the abduction was suspended and resumed on numerous occasions. It was last suspended on 26 June 2009. The investigation is still pending. 81.  The applicants, Ms Zeyna Isayeva and Ms Raisa Isayeva, were born in 1950 and 1981 respectively and live in the village of Valerik, Chechnya. 82.  The first applicant is the mother and the second applicant is the sister of Mr Nurdi Isayev, who was born in 1979. According to the information submitted by the applicants, Mr Nurdi Isayev suffered from mental problems which had arisen as a result of a head wound sustained during the first military campaign in Chechnya in the 1990s. 83.  On the morning of 3 February 2000 Russian security forces started a special operation in Valerik aimed at identifying members of illegal armed groups. As part of the operation the servicemen blocked the perimeter of the village. 84.  On the morning of that day about thirty to thirty-five armed servicemen in camouflage uniforms arrived at the applicants’ house in three APCs with obscured registration numbers.  The servicemen checked the applicants’ identity documents and opened gunfire. On hearing the shots, Mr Nurdi Isayev ran away and the servicemen started shooting at him. The first applicant ran to the servicemen, asking them not to shoot at her son as he was mentally ill. However, the servicemen did not stop firing and the first applicant saw him fall to the ground. She fainted and was taken by her relatives to a neighbour’s house. 85.  On the evening of 3 February 2000, after the servicemen had left the village, the applicants returned home. Their house and their car had been burnt. They did not find Mr Nurdi Isayev at home and did not know what had happened to him. 86.  Between 4 and 9 February 2000 the first applicant searched for Mr Nurdi Isayev, but only in Valerik, as the village was blocked for the large‑scale special operation being carried out by the federal forces in the district, including the nearby village of Katyr-Yurt (for the details of the operation see Isayeva v. Russia, no. 57950/00, § 74, 24 February 2005, and Abuyeva and Others v. Russia, no. 27065/05, § 8, 2 December 2010). 87.  On 9 February 2000 the first applicant found several items of Mr Nurdi Isayev’s clothing with traces of blood on them and first-aid materials next to them in a field adjacent to the village. The first applicant inferred that her son had been given medical aid. She collected all those objects and subsequently submitted them to the investigators. 88.  On an unspecified date in 2002 a neighbour of the applicants’ who had been detained in Chernokozovo remand prison, Ms I., returned home. According to a statement by Ms I. produced by the applicants, while in detention in Chernokozovo she had seen two inscriptions made with a sharp object on the cell wall reading “Nurdi Isayev, village of Valerik” and “3 February 2000”. 90.  On 26 February 2001 the investigators questioned the first applicant, whose detailed description of the circumstances of her son’s abduction was similar to the one submitted to the Court. In addition, she stated that her neighbour, Mr U.Kh., had also been taken away with her son in the same APC and that the special sweeping-up operation had been conducted by servicemen from the Police Special Task Units of the Penza and Yaroslavl regions. 91.  On 26 February 2001 the investigators questioned one of the first applicant’s daughters, Ms R.I., whose statement concerning the abduction was similar to the one given by the first applicant. 92.  On various dates in February and March 2001 the investigators questioned several of the applicants’ neighbours, whose statements concerning the circumstances of the abduction were similar to that of the first applicant. 93.  On 9 June 2005 the investigators again questioned the first applicant, who reiterated her previous statement. 94.  On 9 June 2005 the investigators questioned the applicants’ neighbour Mr U.Kh., who confirmed that he had been abducted by military servicemen along with Mr Nurdi Isayev and taken away in an APC. According to the witness, in the APC he had seen that Mr Nurdi Isayev was in a serious condition as he had sustained gunshot wounds to the head and chest. Mr U.Kh. had been detained for about six days and then released. 95.  On 14 March 2007 the investigators again questioned the first applicant, who reiterated her previous statements.
(b)  Main investigative steps taken by the authorities 96.  On various dates in 2000 the first applicant complained in person about her son’s disappearance to various State authorities. She described the details of the events and requested assistance in the search for him. Her complaints remained unanswered. 97.

The documents submitted show that on numerous occasions between 2001 and 2007 the applicants complained of their relative’s abduction to various authorities and requested assistance in the search for him. They received either no replies or replies to the effect that the investigation was in progress. 102.  The investigation was further suspended and resumed on several occasions in 2007 and 2008 and for the last time on an unspecified date in 2010. 103.  The applicant, Mr Tukhan Idigov, was born in 1933, and lived in the village of Shalazhi, Urus-Martan district, Chechnya. On 5 January 2013 the applicant passed away; his daughter, Ms Tamara Idigova, who was born in 1964 and lives in Grozny, expressed her wish to pursue the application on his behalf. 105.  On the night between 3 and 4 May 2003 Mr Anzor Indigov, his parents and wife were sleeping in the applicant’s house on Lenina Street in Shalazhi (also spelt as Salazhi and Shalazi). 106.  At about 2 a.m. on 4 May 2003 a group of armed men in camouflage uniforms and masks who spoke unaccented Russian broke into the house. The applicant and his relatives thought that the intruders were federal servicemen. Holding the applicant at gunpoint, the servicemen grabbed Mr Anzor Idigov, who was undressed and barefoot, bound his hands, sealed his mouth with adhesive tape and took him away to an unknown destination. Immediately after that two perpetrators returned and ordered the applicant to hand over Mr Anzor Indigov’s identity documents, saying that they were in a pocket of his jacket. 108.  On 4 May 2003 the investigators questioned the applicant and the wife of Mr Anzor Idigov, Ms Kh.E., both of whom provided detailed descriptions of the abduction and stated that the abductors had been military servicemen. 109.

On the night between 2 and 3 March 2006 the second applicant and her son Mr Idris Saayev were in one house, whilst the second applicant’s husband, Mr Kh.S., was in the other one. 126.  At about 5 a.m. on 3 March 2006 the second applicant woke up and saw a group of six armed men in camouflage uniforms. All of them but one, who was in charge of the group, were masked and wearing bulletproof jackets and spherical helmets. They were armed with submachine guns with silencers and pistols secured at the thighs by special rifle belts. The applicants thought they were federal servicemen. 127.  Without any explanation the servicemen requested in unaccented Russian that Mr Idris Saayev produce his identity papers and mobile telephone. They also asked the second applicant about her other son, Mr A.S. Shortly thereafter they took Mr Idris Saayev outside without letting him put on any clothing. When the second applicant and her husband got outside, she saw the perpetrators’ UAZ minivan driving away. 128.  At about 6 a.m. on 3 March 2006 the second applicant, her husband Mr Kh.S. and a relative went to the Staropromyslovskiy department of the interior in Grozny (“the ROVD”) to complain about the abduction of Mr Idris Saayev. A police officer told them that Mr Idris Saayev had been detained by the security forces and that he would return home if he cooperated with them and if the applicants did not lodge any official complaints. The second applicant then decided not to lodge a formal complaint, as suggested by the police officer. 129.  In the days that followed the applicants applied in person to various State authorities seeking assistance in the search for their relative; none of the law-enforcement agencies admitted arresting or detaining Mr Idris Saayev. 130.  About a week later the police officer from the ROVD told the applicants that Mr Idris Saayev had been transferred to Operational Search Bureau no. 2 (“ORB-2”) in Grozny. On the same day the applicants requested information at the bureau but were told that their servicemen had not arrested Mr Idris Saayev. 131.  On an unspecified date a certain Mr R.K. told the applicants that Mr Idris Saayev had been abducted by officers of the Federal Security Service (“the FSB”). Subsequently, the applicants provided Mr R.K.’s phone number to the investigators (see paragraph 138 below). 133.  On 5 April 2006 the investigators questioned the second applicant, whose statement was similar to the one submitted by the applicants to the Court. She pointed out that the perpetrators had been Russian servicemen and that she had tried to find her son without recourse to an official investigation but to no avail. She stated that the abductors had called her neighbours’ phone, asked to speak to her, and told her that they would discuss the details of her son’s release with her. When at the end of March 2006 she had arrived at the place of the meeting suggested by them, she had seen a vehicle with servicemen in it who had filmed her and left without demanding anything. Having realised that her efforts to find her son were unproductive, about four weeks after the abduction she decided to lodge an official complaint about it. 134.  On the same date, 5 April 2006, the investigators questioned the applicants’ neighbours Ms Z.I., Mr R.Zh., Mr A.M., Ms A.D. and Mr R.A., all of whom stated that they had not witnessed the abduction but had learnt about it from the applicants. 136.  On 20 July 2007 the investigators questioned the first applicant, whose statement was similar to the one given by the second applicant.
(b)  Main investigative steps taken by the authorities 137.  On 5 April 2006 the investigators examined the crime scene. No evidence was collected. The applicants provided the investigators with Mr Idris Saayev’s photo. 138.  On 6 April 2006 the Staropromyslovskiy district prosecutor’s office (“the district prosecutor’s office”) opened criminal case no. 53037. 144.  On 15 August 2007 the first applicant complained to the Staropromyslovskiy District Court (“the district court”) stating that the investigation had been unlawfully suspended and requested that the court order the investigators to take effective steps to solve the crime. 146.  On 11 September 2007 the district court dismissed the first applicant’s complaint, stating that the investigation had been resumed on 18 August 2007. 152.  In 2002 the applicant and Mr Rustam Amerkhanov, who suffered from a brain tumour, resided in the village of Shalazhi (also spelt Shalazi), in the Urus-Martan district. At the material time the settlement was under the full control of the federal forces; a number of military units and law‑enforcement agencies were stationed therein. 154.  On the morning of 4 November 2002 the applicant found out that her son had not visited his friend’s house and that on the night between 3 and 4 November 2002 he had been detained by servicemen from the 47th unit of the Special Task Force Division (DON-2) of the Internal Troops of the Russian Ministry of the Interior. 155.  On 5 November 2002 the applicant lodged an abduction complaint with the Urus-Martan district prosecutor’s office. On the same date the interim district prosecutor, Mr D.Z., obtained confirmation from the Urus‑Martan district department of the interior (ROVD) that Mr Rustam Amerkhanov had been brought by servicemen to the ROVD at about 8 a.m. on 4 November 2002 for an identity check and released about three hours later. 156.  On the same date the applicant, with two of her relatives and the interim district prosecutor, spoke to the officer in charge of the military unit who had detained the applicant’s son. At first the officer stated that Mr Rustam Amerkhanov had been released shortly after the arrest, but then admitted that he had been taken to the ROVD. 157.  On the morning of 6 November 2002 (in the documents submitted the date is also referred to as 4 and 9 November 2002) the interim district prosecutor Mr D.Z. confirmed to the applicant that her son was detained on the premises of the ROVD and that he would be released shortly. The applicant was told to wait for her son outside the ROVD. 158.  Later on the same day, at about 4 p.m. the applicant, who had waited since the morning, spoke to the interim district prosecutor Mr D.Z., who told her that her son was not in fact in the ROVD and that his whereabouts were unknown. A week later Mr D.Z., who had been on a service mission in Chechnya, left the Republic to return to the place of his permanent employment. Prior to his departure he told the applicant that the deputy head of the ROVD, Mr V.B., had questioned Mr Rustam Amerkhanov after the arrest. 159.  On an unspecified date the applicant contacted Mr V.B. and he confirmed to her that he had interviewed her son, that it had been established that the latter had not participated in illegal armed groups and that therefore her son had been released. 161.  In their submission on the facts the Government submitted that Mr Rustam Amerkhanov had been detained by the 47th military unit on the night between 3 and 4 November 2002 and at 7 or 8 a.m. on 4 November 2002 he had been taken to the Special Task Unit (OMON), which was staffed by servicemen from the Omsk region of Russia and was stationed on the premises of the former fruit canning factory. Mr Rustam Amerkhanov was handed over to the head of the OMON unit, officer V.G. 162.  At about 9.15 a.m. on 4 November 2002 Mr Rustam Amerkhanov was taken to see the deputy head of the Urus-Martan ROVD, officer V.B., who signed a statement to that effect. At the ROVD the identity of the applicant’s son was verified and he was interviewed. Shortly thereafter, as his involvement in illegal armed groups had not been confirmed, on the same date, 4 November 2002, Mr Rustam Amerkhanov was released. His whereabouts have been unknown since. 163.  On 6 November 2002 the investigators questioned officer V. G., who confirmed that his unit had detained Mr Rustam Amerkhanov at about 2 a.m. on 4 November 2002. The officer personally interviewed him and concluded that he was not involved in illegal activities. At about 8 a.m. on 4 November 2002 he received an order from the deputy head of the Urus‑Martan ROVD to hand Mr Rustam Amerkhanov over to the police. At about 9.15 on the same morning the witness brought Mr Rustam Amerkhanov to the deputy head of the ROVD, officer V.B. The witness explained that he had initially told the applicant that her son had not been arrested by his unit as he had been concerned that “it would lead to disturbances among the local residents”. 164.  On 6 November 2002 the investigators questioned the applicant, whose statement was similar to the one submitted to the Court. 165.  On 11 November 2002 the investigators questioned the deputy head of the ROVD, officer V.B., who stated that between 9 a.m. and 11 a.m. on 4 November 2002 he had interviewed Mr Rustam Amerkhanov and then released him. Operational search officer I.O. had taken Mr Rustam Amerkhanov to the entrance and the latter had left. 166.  On 12 November 2002 the investigators questioned the operational search officer Mr I.O., who stated that on the morning of 4 November 2002 Mr Rustam Amerkhanov had been brought to the ROVD and taken to the office of officer V.B., who had interviewed him. After the interview officer V.B. had asked the witness to take Mr Rustam Amerkhanov to the gates and release him. The witness had taken the applicant’s son to the gates and the latter had left. 167.  On 15 November 2002 the investigators questioned the applicant, who reiterated her previous statement. In addition, she stated that the deputy head of the ROVD officer V.B. had “blatantly lied” to the investigators that he had released her son on 4 November 2002 as she and two of her relatives, Ms T.A. and Ms Kh.A., and a friend had spent the entire day at the entrance to the building to no avail. 168.  On 15 November 2002 the investigators questioned the applicant’s sister, Ms T.A., who confirmed the statement the applicant had given on the same date. 169.  On 13 April 2004 the head of the Shalazhi village administration, Mr R.M., submitted a written statement to the investigators which was similar to the one the applicant had given on 15 November 2002. He stressed that for two days officer V. B. had deliberately lied to him and the applicant, denying Mr Rustam Amerkhanov’s arrest, and that this officer must have been responsible for the disappearance of the applicant’s son. 170.  On 29 April 2004 the investigators again questioned the applicant’s sister Ms T.A., who reiterated her previous statement. In addition, she stated that a few days after the disappearance of Mr Rustam Amerkhanov officer V.B. had told her husband, Mr N.A., that Mr Rustam Amerkhanov had been transferred to another law-enforcement agency. 171.  On 28 May 2004 the investigators again questioned officer V.G., who reiterated his statement of 6 November 2002 and added that on the evening of 4 November 2002 he had spoken to the applicant and confirmed that Mr Rustam Amerkhanov had been apprehended by his unit.
(b)  Main investigative steps taken by the authorities 172.  On 12 November 2002 the Urus-Martan district prosecutor’s office opened criminal case no. 61151 under Article 105 of the Criminal Procedure Code (murder) (in the documents submitted also stated as under Article 126 of the Criminal Procedure Code (abduction)). 175.  On 25 September 2003 the investigation was resumed and then again suspended on 25 October 2003. The applicant was not informed thereof. 176.  On 13 April 2004 the investigation was resumed and then again suspended on 15 May 2004. The applicant was not informed thereof. 178.  On 1 July 2004 the investigators examined two registration logs for the period between August 2003 and July 2004: the first log contained the names of persons taken to the Urus-Martan ROVD and the second log contained the names of those detained on its premises. No entries concerning Mr Rustam Amerkhanov were found. 180.  On 5 August 2004 the investigators questioned several of the applicant’s neighbours, all of whom stated that they had learnt of Mr Amerkhanov’s disappearance from others. 181.  The documents submitted show that on numerous occasions between 2002 and 2007 the applicant wrote to various law-enforcement agencies and military authorities, describing the circumstances of her son’s disappearance and the acknowledgement of his arrest by the military and police officers and asking for assistance in establishing his whereabouts. 182.  On 6 April 2010 the head of the Urus-Martan ROVD informed the investigators that the registration log of detainees in the ROVD for the year 2002 could not be examined as it had been lost. 184.  The applicants are:
(1)  Ms Lyubov Dubas, born in 1959;
(2)  Mr Bislan Magomadov, born in 1954;
(3)  Ms Sara Ozdoyeva, born in 2001, and
(4)  Mr Riyyadus-Solikhiyn Ozdoyev, born in 2003.
The applicants live in the village of Katyr-Yurt, Chechnya. 185.  The first and second applicants are the parents of Ms Milana Ozdoyeva, who was born in 1982. The third and fourth applicants are her children. 187.  At about 5 p.m. on 26 December 2003 a group of servicemen from a State agency arrived at the applicants’ house in Katyr-Yurt looking for Ms Milana Ozdoyeva. The servicemen had a copy of Ms Milana Ozdoyeva’s identity card with them and asked about her whereabouts. The first applicant explained that her daughter and her husband were living on Sadovaya Street in the village of Sleptsovskaya, Ingushetiya. Then the servicemen left. 188.  On 27 December 2003 the first applicant complained to the Achkhoy-Martan Department of the Interior (“the ROVD”) about the servicemen’s visit. The deputy head of the ROVD assured her that it had been a mistake. 190.  On 10 January 2004 the first applicant learnt that while she had been at work with her daughter Ms Milana Ozdoyeva at the Achkhoy‑Martan administration, the servicemen had again visited her house looking for her daughter. Then they had gone to the administration and questioned Ms Milana Ozdoyeva on its premises for about thirty minutes. The first applicant learnt from one of the police officers, Mr M.E., that her daughter Ms Milana Ozdoyeva was suspected of planning to become a suicide bomber.
(b)  Abduction of Ms Milana Ozdoyeva 191.  On the night between 18 and 19 January 2004 the applicants, Ms Milana Ozdoyeva and a relative, Mr A.M., were at home at 68 Lenina Street, Katyr-Yurt. 192.  At about 2 a.m. on 19 January 2004 a group of about fifteen armed men in camouflage uniforms and masks broke into the applicants’ house. The intruders arrived in several vehicles which they parked nearby; some of them carried portable radios. All the intruders spoke unaccented Russian. The applicants inferred that they were federal servicemen. Having searched the house without giving explanations, the servicemen ordered Ms Milana Ozdoyeva to leave with them. One of the servicemen told the first applicant that her daughter would return later in the morning. 193.  The first applicant and Mr A.M. followed the servicemen outside and tried to follow the abductors but they had to return to the house due to the curfew. 195.  Shortly after Ms Milana Ozdoyeva had been taken away, early in the morning on 19 January 2004 the first and second applicants complained to the head of the local administration about their daughter’s abduction. 196.  Later that morning the first applicant and a relative, Ms A.A., went to the ROVD, where police officers told them that nobody had been brought to the police station that night. The first applicant lodged a written complaint about the abduction with the on-duty officer and then with the Achkhoy-Martan district prosecutor’s office. 197.  On the evening of 19 January 2004 the applicants learnt that the servicemen who had taken Ms Milana Ozdoyeva away had also raided the house of another resident of the village, Mr M.T., but the latter had not been at home. They also learnt that their daughter’s abductors had arrived in a military Ural lorry, which they had parked in the centre of Katyr-Yurt before proceeding to the house on foot. 198.  On 26 January 2004 the first applicant saw one of the servicemen who had visited her house on 10 January 2004, Mr S., at the offices of the local administration. He told her that the theory that Ms Milana Ozdoyeva was a suicide bomber had not been confirmed. 199.  On 19 January 2004 the investigators questioned the first and second applicants, whose description of the abduction was similar to the one submitted to the Court. 200.  On 19 January 2004 the investigators also questioned the applicants’ relative Mr A.M., whose statement concerning the circumstances surrounding the abduction was similar to that of the first and second applicants. 201.  On the same date, 19 January 2004, the investigators questioned the applicants’ neighbours Mr Sh.M., Mr M.M., and Mr A.-Ya. M., all of whom stated that they had learnt of the abduction from the applicants. 202.  On 30 January 2004 the investigators again questioned the first applicant, who reiterated her previous statement and stressed that among the servicemen who had visited the house in December 2003 looking for Ms Milana Ozdoyeva had been a police officer from the ROVD, Mr M.E., who had told her that Ms Milana Ozdoyeva’s late husband had been an active member of illegal armed groups and that Ms Milana Ozdoyeva herself had decided to become a suicide bomber. 203.  On 30 January and 1 February 2004 the investigators again questioned the applicants’ relative Mr A.M., whose statement was similar to that of the first applicant given on 30 January 2004. 204.  Between 30 January and 5 February 2004 the investigators questioned the applicants’ neighbours Ms R.K., Mr T.M. and Ms M.I. as well as previously questioned Mr A.-Ya. M., all of whom stated that they had learnt of the abduction from the applicants. 206.  On various dates in February 2004 the investigators questioned three operational-search officers from the Achkhoy-Martan ROVD, Mr V.Ch., Mr M.E. and Mr D.I., all of whom stated that on 5 January 2004 officers from a special security service had arrived at their police station and asked the deputy head of the ROVD, officer Sh.P., to assign local police officers to go with them to Katyr-Yurt to speak with Ms Milana Ozdoyeva. Following the orders of the head of the ROVD, the police officers had accompanied the officers from the security service to the applicants’ house, where the latter had questioned Ms Milana Ozdoyeva about her life in Ingushetia, her late husband and whether she had been pressurised to become a suicide bomber. 207.  On an unspecified date in February 2004 the investigators questioned the deputy head of the ROVD, officer Sh.P., whose statement was similar to those given by police officers Mr V.Ch., Mr M.E. and Mr D.I. In addition, he stated that the theory of the involvement of the Federal Security Service in Ms Milana Ozdoyeva’s abduction had not been confirmed.
(b)  Main investigative steps taken by the authorities 208.  On 19 January 2004 investigators from the Achkhoy-Martan district prosecutor’s office examined the crime scene. No evidence was collected. 211.  On 14 February 2005 the Achkhoy-Martan District Court granted the first applicant’s claim and declared Ms Milana Ozdoyeva a missing person. On 14 August 2009 it declared her dead. 212.  The documents submitted show that on numerous occasions between 2004 and 2008 the applicants contacted various law-enforcement agencies, military authorities and local courts, asking for assistance in establishing the whereabouts of Ms Milana Ozdoyeva and trying to obtain information about the progress of the investigation. For instance, on 26 February 2008 the first applicant complained to the Achkhoy-Martan District Court about the investigators’ refusal to provide her with full access to the case file. On 30 April 2008 the Supreme Court partially allowed the complaint. 213.  The investigation in the criminal case was suspended and resumed on several occasions. The last suspension of the proceedings took place on 10 July 2008. 215.  The applicants are:
(1)  Ms Tamara Shakhbiyeva, who was born in 1955,
(2)  Mr Khuseyn Shakhbiyev, who was born in 1950,
(3)  Mr Saifulla Shakhbiyev, who was born in 2000, and
(4)  Ms Khedi Khizrayeva, who was born in 1980.
The first and second applicants live in Tsotsi-Yurt (also referred to as Oktyabrskoe), Kurchaloy district, Chechnya; the third and fourth applicants live in Grozny. 216.  The first and second applicants are the parents of Mr Ezir-Ali Shakhbiyev, who was born in 1974, Mr Abzu (also spelt Abza) Shakhbiyev, who was born in 1977 and Mr Sayd-Magomed Shakhbiyev, who was born in 1978. The third applicant is the son of Mr Ezir-Ali Shakhbiyev and the fourth applicant is his wife. 217.  At the material time the applicants resided in a family house together with Mr Ezir-Ali Shakhbiyev, Mr Abzu Shakhbiyev and Mr Said‑Magomed Shakhbiyev. Mr N. Ochayev was also staying in their house as he had been hired by the first and second applicants to work in his excavator on their property. 218.  Early in the morning on 4 September 2000 Russian servicemen launched a “sweeping-up” operation in the settlement of Tsotsi-Yurt. The settlement was surrounded by servicemen riding in URAL lorries and military UAZ cars. Helicopters were flying over the area. 219.  At around 5 a.m. on 4 September 2000 an APC and several UAZ cars and URAL lorries arrived at the applicants’ house. A group of twenty‑five to thirty masked servicemen in camouflage uniforms broke in. They blindfolded Mr Ezir-Ali Shakhbiyev, Mr Abzu Shakhbiyev, Mr Said‑Magomed Shakhbiyev and Mr N. Ochayev with torn sheets and took them outside. The servicemen put Mr Ezir-Ali Shakhbiyev in his own VAZ‑2106 car and the other three men in a URAL lorry and drove away. 220.  It appears that at least four other men were arrested in Tsotsi-Yurt that morning, including the second applicant’s brother, Mr Khizir Agamerzayev (also referred to as Agmurzayev). A URAL lorry had driven him to the centre of the settlement. 221.  Several days later the applicants learnt from anonymous sources that the three Shakhbiyev brothers and Mr N. Ochayev had been taken to the Main Federal Military Base in Khankala, Chechnya. 222.  On 13 September 2000 Mr N. Ochayev and Mr Khizir Shakhbiyev and three other Tsotsi-Yurt residents were released at a crossroads on the Rostov-Baku highway in the vicinity of Mesker-Yurt, where they had been brought in an APC. A man from a neighbouring village drove them home. 223.  According to Mr Khizir Agamerzayev, after the arrest he, Mr Ezir‑Ali Shakhbiyev, Mr Abzu Shakhbiyev, Mr Said-Magomed Shakhbiyev and Mr N. Ochayev were put in separate cells in a basement. Mr Khizir Agamerzayev was beaten up and questioned about a certain Mr Yakub from Tsotsi-Yurt, the Barayevs and the Akhmadovs, allegedly members of illegal armed groups. On 12 September 2000 in the morning Mr Khizir Agamerzayev had seen the servicemen take the three Shakhbiyev brothers outside and put them in military vehicles. 225.  On 14 December 2003 the investigators questioned the first applicant, whose statement concerning her sons’ abduction was similar to the one submitted to the Court. She pointed out that in her opinion the abduction had been perpetrated by military servicemen. 226.  On 15 December 2003 the investigators questioned the second applicant, whose statement was similar to the one given by the first applicant. 227.  On 25 May 2005 the investigators again questioned the second applicant, who reiterated his previous statement and added that Mr Khizir Agamerzayev had been arrested together with his sons but released sometime later. At some point later Mr Khizir Agamerzayev had moved to Nazran, Ingushetia. 228.  On 4 and 5 February 2010 the investigators again questioned the first and second applicants, who reiterated their previous statements. 229.  On 9 February 2010 the investigators questioned the son of the first and second applicants, Mr A.Sh., whose statement concerning his brothers’ abduction was similar to the ones given by his parents, the first and second applicants. 230.  On various dates between 9 and 24 February 2010 the investigators questioned a number of witnesses, including the first and second applicants’ relatives and neighbours, the fourth applicant, Mr Khizir Agamerzayev and Mr N. Ochayev. All of them gave statements corraborating those given by the first and second applicants. In addition, Mr N. Ochayev and Mr Khizir Agamerzayev provided a detailed description of their detention on the premises of the military base in Khankala after the abduction. Both of them stated that they had been beaten and questioned about their alleged involvement in illegal armed groups and that the Shakhbiyev brothers had remained in detention while they had been released.
(b)  Main investigative steps taken by the authorities 231.  On 11 November 2000 the Kurchaloy ROVD refused to initiate criminal proceedings in connection with the abduction of the three Shakhbiyev brothers as their arrest had taken place during a “sweeping-up” operation. 232.  On 11 July 2001 the first applicant again complained about her sons’ abduction. On 13 August 2001 the Kurchaloy district prosecutor’s office opened criminal case no. 39051. 233.  On 13 October 2001 the investigation was suspended and then resumed on 18 November 2003 upon the supervising prosecutor’s orders. 234.  On 18 December 2003 the investigation was suspended again and then resumed on 20 April 2005 upon the supervising prosecutor’s orders. 235.  On 25 May 2005 (in the documents submitted the date is also given as 27 May 2005) the investigators examined the crime scene. No evidence was collected. 237.  On 14 January 2010 the first applicant requested information on the progresss of the investigation and permission to access the investigation file. 238.  On 28 January 2010 the investigators resumed the proceedings but refused to grant the first applicant permission to access the case file as she did not have victim status in the criminal case. 241.  On 28 April 2010 the investigators granted the first applicant’s request for access to the case file by letting her consult a few documents. 243.  The applicants are:
(1)  Ms Saykhat Dubayeva, who was born in 1953,
(2)  Mr Shirvani Dubayev, who was born in 1952,
(3)  Ms Zalina Dubayeva, who was born in 1996,
(4)  Mr Shamkhan Dubayev, who was born in 1999 and
(5)  Mr Shamil Dubayev, who was born in 1986.
The applicants live in Berkat-Yurt, Chechnya. 244.  The first and second applicants are the parents of Mr Sharpudi (also spelled as “Sharfutdi”) Dubayev, who was born in 1977. The third and fourth applicants are his children and the fifth applicant is his brother. 245.  On 20 November 2002 Mr Sharpudi Dubayev and four other men, including Mr R.A. and Mr A.I., were driving in a VAZ-2106 car with the registration number X582 AB95 when, about one and a half kilometres from the village of Berkat-Yurt, they were stopped by a group of about twenty or twenty-five masked military servicemen in camouflage uniforms driving in two APCs. The servicemen belonged to the 34th brigade of the military forces which at the material time guarded the oil pipeline which ran adjacent to the settlement. 246.  The servicemen asked the car passengers for their identity documents; then they dragged the men out of the vehicle, forced them into the APCs and took them to the military base where the 34th brigade was stationed. 247.  The applicants’ relative, Mr Sharpudi Dubayev, was detained at an unidentified location in the same cell as Mr R. A. According to the latter, both of them were tortured and questioned. 248.  On 23 November 2002 all of the detained men, save for the applicants’ relative, were blindfolded, taken to an unidentified location and released, whereas Mr Sharpudi Dubayev has been missing ever since. 249.  On 8 September 2003 the investigators questioned the first and second applicant and Mr R.A. Their statements concerning the circumstances surrounding the abduction were similar to those submitted to the Court. 251.  On 8 January 2004 the investigators questioned Mr A.I. and Mr R.A. Their statements concerning the abduction were similar to the ones submitted to the Court. 252.  On various dates in February and March 2011 the investigators questioned the first applicant and two police officers, whose statements did not provide new information.
(b)  The main investigative steps taken by the authorities 253.  On 28 September 2003 the Grozny district prosecutor’s office initiated a criminal investigation into the abduction under Article 126 § 2 of the Criminal Code (aggravated kidnapping). The case file was given the number 42169. 254.  In October 2003 the investigators sent information requests to various authorities. On 15 October 2003 the Grozny district department of the Federal Security Service (FSS) informed the investigators that Mr Sharpudi Dubayev was a member of illegal armed groups who had undergone specialized explosives training in a terrorist camp. 258.
