4.  The applicant was born in 1954. She is the mother of Said-Emin (also known as Said-Ali) Sambiyev, who was born in 1978. At the material time she lived in Tevzan; she currently lives in Grozny, Chechnya. 5.  At the material time the applicant’s son Said-Emin Sambiyev worked for the Security Service of the Chechen President. 6.  On 13 August 2003 Said-Emin Sambiyev and his colleague Mr V.M. were in a taxi going from the village of Ulus-Kert to the village of Makkhety. Their vehicle was stopped in the village of Tevzan (in the submitted documents the place was also referred to as Tevzani and Kirov‑Yurt), in the Vedeno district, at a checkpoint manned by servicemen of military unit no. 28337-A (in the submitted documents also referred to under the number 28337). 7.  Said-Emin Sambiyev and Mr V.M. were detained at the checkpoint by the servicemen and taken to the location of the 45th Airborne Forces Regiment in the village of Khatuni (also spelled Khattuni), in the Vedeno district of Chechnya. 8.  The abduction of the two men was witnessed by Mr I.G., whose car was also stopped at the checkpoint in Tevzan. He saw that two young men were being detained by servicemen at the checkpoint; he recognised one of them as Said-Emin Sambiyev, who worked for the Security Service. Mr I.G. asked the servicemen about the reasons for the arrest, but the officers refused to answer and told him that the two young men would be taken for an identity check to the 45th regiment’s base, in the military base in Khatuni.
(b)  Subsequent events 9.  On 25 August 2003 Mr V.M. was released from detention in Khatuni. That day a number of his relatives as well as two of his colleagues from the Security Service and the head of the Service, Mr S.Kh., waited for his release at the 45th regiment’s base. Mr I.G. picked him up in Khatuni and drove to Shali. In the car Mr V.M. told Mr I.G. that during his detention in Khatuni he had seen Said-Emin Sambiyev twice. Said-Emin Sambiyev had been beaten up and could barely speak. According to Mr I.G., the officers in Khatuni promised to release Said-Emin Sambiyev one day after the release of Mr V.M. 10.  On the same date the applicant met Mr V.M. and asked him about her son. Mr V.M. told her that he and Said-Emin Sambiyev had been detained in separate pits in the ground which were situated not far from each other. During the detention Mr V. M. had had a sack over his head. At some point he had called the name of Said-Emin Sambiyev and the latter had responded, his voice was weak and muffled as if he also had a sack over his head. After that the two men had been questioned together; during the questioning both of them had sacks over their heads. Shortly before his release Mr V. M. had seen the applicant’s son. Said-Emin Sambiyev had been wearing different clothing, galoshes and tracksuit bottoms. When the applicant asked Mr V. M. how he had managed to get released, he told her: “I was just trying to save my life” and did not explain anything further. According to Mr V. M., he had been told by the abductors that Said-Emin Sambiyev would be released the day after him. 11.  According to the applicant, in the autumn of 2003 Mr V. M. moved to Moscow and then to Austria. 12.  In support of her statements the applicant submitted the following documents: her own statement dated 7 July 2006; a statement by Mr V.M., undated, a statement by Mr I.G. dated 8 July 2006 and copies of the documents received from the authorities. 13.  The Government did not challenge the matter as presented by the applicant. According to their observations of 1 July 2009, it was established that on 13 August 2003 Mr S-E. Sambiyev and Mr V.M. were, with an unidentified person, travelling in a car from Ulus-Kert in the Shatoi district to Makhkety in the Vedeno district. They had been stopped by military servicemen in armoured personnel carriers. After that the two men had been taken to the location of the military unit stationed in Khatuni. Eleven days later Mr V.M. had been released, while the whereabouts of Mr S.-E. Sambiyev has not been established since. 14.  According to the applicant, she contacted, both in person and in writing, various official bodies asking for help in establishing the whereabouts of her son Said-Emin Sambiyev. The applicant did not retain copies of her written requests lodged with various State authorities from August to October 2003; however, she kept copies of a number of her further complaints and submitted them to the Court. An official investigation was opened by the local prosecutor’s office. The relevant information is summarised below. 15.

On 28 February 2006 the applicant again complained to the district prosecutor. She reiterated that her son had been abducted by servicemen of the 45th regiment, stationed in Khatuni. She pointed out that Mr V.M. had been released on 25 August 2003 and that a number of persons, including his relatives and colleagues, had been waiting at the regimental base for his release. Further, the applicant complained about lack of information about the investigation and requested to be provided with an update on its progress. 34.  On 14 September 2006 the applicant’s representatives wrote to the district prosecutor and the Chechnya prosecutor. They described the circumstances of Said-Emin Sambiyev’s disappearance and stated that he had been taken away by servicemen of the 45th regiment and detained for at least ten days at the regiment’s base in Khatuni. They requested that the investigators provide the following information: whether any progress had been made by the investigation; whether the investigators had identified the perpetrators and the witnesses to the abduction; whether the registry records of military unit no. 28337-A had been requested and examined; whether the applicant had been granted victim status in the criminal case, and whether she could be provided with access to the investigation file. Finally, they requested the investigators to resume the investigation in the criminal case and to provide the applicant with copies of procedural decisions. 35.  On 13 October 2006 the district prosecutor’s office informed the applicant that they had taken all possible investigative measures; that on 26 May 2005 they had suspended the investigation in the criminal case; and that on 13 October 2006 the deputy district prosecutor had overruled this decision and the investigation had been resumed. According to the letter, the applicant was allowed to familiarise herself only with those documents from the case file which reflected investigative steps taken with her participation. 36.  On 25 January 2007 the applicant’s representatives reiterated their requests for information of 14 September 2006 to the district prosecutor and the Chechnya prosecutor. In response, on 12 February 2007 the Chechnya prosecutor’s office forwarded her request to the district prosecutor’s office for examination. 37.  On 14 February 2007 the district prosecutor’s office informed the applicant that on 13 December 2006 they had suspended the investigation in the criminal case for failure to identify the perpetrators. 38.  On 20 February 2007 the district prosecutor’s office informed the applicant that they could not establish the truth of what had happened with the abduction of Said-Emin Sambiyev by servicemen of military unit no. 28337, as the key witness in the case, Mr V.M., had absconded to Europe. The letter also stated:
“... there is information provided by the FSB about the involvement of Sambiyev and Mr V.M. in the activities of a criminal group in the Shatoi district of Chechnya and their participation in the attack on Ulus-Kert in May 2003... in connection with the complaints of Sambiyev’s mother [the applicant], the investigation in the criminal case had been resumed on several occasions... today it is possible for the investigation to establish the identity of those who had been involved in the unlawful detention of Said-Emin Sambiyev; relevant investigative measures have been planned and would be taken by the prosecutor’s office ...” 39.  The applicant received no further information from the authorities concerning the investigation into her son’s disappearance. 40.  On 2 October 2003 the applicant complained about her son’s abduction to the district prosecutor’s office. 41.  On the same date the district prosecutor’s office opened an investigation into the disappearance of Said-Emin Sambiyev. 42.  On the same date, 2 October 2003, the investigators granted the applicant victim status in the criminal case and questioned her. She stated that at about 3 p.m. on 15 August 2003 Ms R.M. had arrived at her house and told her that their sons, S.-E. Sambiyev and V.M., had been arrested by military servicemen at a checkpoint next to Tevzan. Then both women had gone to Mesker-Yurt to the Security Service of the Chechen President, where the applicant’s son had worked. The commander of S.-E. Sambiyev, Mr S. Kh., had informed them that their sons had gone to Makkhety to visit V.M.’s relatives. On the following day, 16 August 2003, the applicant with her son’s colleague Mr Kh. had gone to Tevzan. From the local residents she had learnt that on 13 August 2003 on the road leading to Vedeno military servicemen in APCs had stopped a car and two young men had got out of it. From the descriptions of the local residents the applicant had understood that these two young men were her son and Mr V.M. Some of the local residents had approached the men and asked them whether they needed any help. S.-E. Sambiyev and V.M. had told them that they did not need any help. Having spoken with the locals the applicant and Mr Kh. had gone to the military unit in Khatuni. The servicemen at the entrance checkpoint had refused to speak to them. On 24 August 2003 Mr V.M. had returned home and told the applicant that on 13 August 2003 he and her son had been detained by military servicemen on the road next to Tevzan. The servicemen had taken away their service guns and identification documents. Then they had taken the men to the regimental base in Khatuni. Mr V.M. had spent eleven days there. Throughout this time he had seen the applicant’s son on two occasions; most of the time both of them had black sacks over their heads which had been removed by the abductors when the two men had been taken out for interrogations. S.-E. Sambiyev and Mr V.M. had been beaten and tortured with electric shocks. After speaking with Mr V.M. the applicant had gone to her son’s commander Mr S.Kh. The latter had told her that the military servicemen had handed her son over to the Grozny FSB. On several occasions the applicant had asked officers at the Grozny FSB about her son, but they had denied arresting him or having him transferred to their office. 43.  On 9 October 2003 the investigators granted Mr V.M. victim status in the criminal case and questioned him. He stated that from May 2003 he had worked as an officer (an intelligence agent) in the Security Service of the Chechen President. On 13 August 2003 he and S.-E. Sambiyev had driven to Dutz-Khutor in a private car. They had been on an intelligence mission to find a storage facility built by illegal armed groups in the vicinity of the village of Selmetkhauzen. Between Makkhety and Khatuni, their car had been stopped by masked armed military servicemen in two APCs. Without giving any explanation the servicemen had taken away their identity documents and service guns. After that they had taken the two men to the military base in Khatuni, where they had placed the men separately in two pits with water in them. According to the witness, he had spent three days in the pit; he had frequently been beaten, tortured and questioned by the servicemen about the places where members of illegal armed groups lived and stored their firearms. He had told them everything he knew. After that they had taken him by helicopter to a place where the military servicemen had found and collected a number of mobile phones, satellite radio devices, ammunition and firearms. This operation had been carried out by a group of servicemen of various ethnic backgrounds. One of them, who had beaten Mr V.M. the most, had teeth made from yellow metal. Mr V.M. had not seen his face as the officer had been masked. The man in charge of the group was nicknamed “the American” (“Американец”), he was around thirty years old and dressed in a clean uniform with red, black, blue and white camouflage patterns on it. On 24 August 2003 the witness had seen the applicant’s son, when the latter was being taken out of an APC.S.-E. Sambiyev had been beaten; he had been accused of murdering a police officer and pressurised to confess to blowing up an APC two or three days prior to his arrest. After Mr V.M. had been released, the military officers had not returned his service machine gun, identity documents and thirty bullets. As a result of the beatings during the detention Mr V.M. had had to undergo outpatient medical treatment until 10 September 2003. 44.  In the autumn of 2003 Mr V.M. went to live permanently in Europe. 45.  On 9 October 2003 the investigators questioned Mr S.Kh., the head of a special platoon of the Security Service of the Chechen President. The applicant’s son had served in his platoon as an intelligence officer. At some point he had been informed that S.-E. Sambiyev and Mr V.M. had been detained by military servicemen. He had immediately gone to the military unit SSG-10 (“Специальная Сводная Группа-10”) stationed in Khatuni, whose commander Mr M. had told him that the two men had been detained on the site of a special division of the military unit under the command of a man nicknamed “the American”. After that the witness had gone to the military unit stationed in Khatuni to speak with its command, but to no avail. On 25 August 2003 the witness, with the assistance of Mr M., had managed to release Mr V.M.; the latter had had traces of beatings on his body, and his hands had the marks of handcuffs. As for the applicant’s son, the witness had been told that S.-E. Sambiyev was suspected of killing two police officers in the Shatoi district and in connection with this he had been handed over from the military unit to the Chechnya FSB for an investigation of the killings. 46.  On 2 December 2003 the investigators suspended the investigation in the criminal case for failure to identify the perpetrators. The applicant was informed about this decision. 47.  On 11 May 2004 the interim district prosecutor ordered the investigators to resume the investigation and take the following investigative steps within fifteen days:
“... At the moment it is necessary to take a number of investigative steps in order to forward the criminal case for further investigation to the military prosecutor’s office in accordance with the rules of jurisdiction:
...
-  to question Mr V.M. again about the circumstances of the case ...;
-  to identify local residents who witnessed the arrest;
-  to identify the service guns of S.-E. Sambiyev and Mr V.M. [which were taken away by the abductors];
-  to identify whether the guns were put on the search list or whether they were confiscated from illegal armed groups ...” 48.  On 24 May 2004 the investigation of the abduction was resumed. The applicant was informed about the decision. 49.  On 24 May and 4 June 2004 the investigators forwarded a number of requests for information to various prosecutors’ offices in Chechnya and the Vedeno ROVD concerning the possible whereabouts of the applicant’s son. According to the replies, he had not been detained by law-enforcement agencies, was not being detained and his corpse had not been found. 50.

On 26 May 2005 the investigation in the criminal case was suspended for failure to identify the perpetrators. The applicant was informed about this decision. 55.  On 13 October 2006 the supervising prosecutor ordered the investigators to resume the investigation and take a number of steps. 56.  On various dates in October and November 2006 the investigators forwarded a number of requests to various law-enforcement agencies asking whether the latter had detained the applicant’s son, opened criminal proceedings against him, or whether they had any negative information about him. 57.  On 12 December 2006 the investigators again questioned the applicant who confirmed her statement given on 2 October 2003 (see paragraph 42 above). 58.  On 13 December 2006 the investigation in the criminal case was suspended for failure to identify the perpetrators. The applicant was informed about this decision. 59.  On 23 December 2006 the Chechnya FSB informed the investigators that according to their database S.-E. Sambiyev was a member of an illegal armed group, that on 25 May 2003 he had participated in an attack on the village of Ulus-Kert; that on 29 July 2003 he had surrendered and on 5 August 2003 he had been pardoned by the authorities. 60.  On 9 January 2007 the Vedeno ROVD informed the investigators that Mr V.M. had left Russia and was living in Europe, and that they had no information confirming any involvement of the applicant’s son or Mr V.M. in illegal armed groups. 61.  On 14 March 2007 the supervisory prosecutor ordered the investigators to resume the investigation and take a number of investigative steps. The applicant was informed about this decision. 62.  On 22 March and 3 April 2007 the investigators forwarded requests to military unit no. 20102 and the Chechnya FSB asking for information about the military unit SSG-10 which had been stationed in Khatuni between 1 and 31 August 2003 and its commander Mr M. They also requested information about the commander of the special group with the nickname “the American”. In reply the FSB informed the investigators that they did not have any relevant information. 63.  On 22 March and 3 April 2007 the investigators forwarded a request to military unit no. 45807 asking for information about the military servicemen of this unit who had been stationed in Khatuni between 1 and 31 August 2003 and their current addresses. 64.  On 24 March 2007 the investigators again questioned Mr S.Kh. who stated that he did not know for sure whether Mr M. had been the commander of the military unit SSG-10, but that he had seen him on the site of the military unit. 65.  On 29 March 2007 the investigators questioned Mr A.A., who stated that in 2003 he was working as a taxi driver. On an unspecified date in August 2003 a man had asked him to pass on to the relatives of Said-Emin Sambiyev and Mr V.M. that the two men had been arrested at the checkpoint. 66.  On 5 April 2007 the investigators questioned Ms R.M., the mother of Mr V.M., who stated that in the summer of 2003 her son and Said-Emin Sambiyev had been working somewhere in Mesker-Yurt and that their commander’s name was Mr S.Kh. At some point later, residents of Ulus‑Kert had told her that her son and S.-E. Sambiyev had been detained by military servicemen. She had gone to the applicant and told her about it. Then both women had gone to Mesker-Yurt to see their sons’ commander. After that the women had gone to the military unit in Khatuni, but they had not been allowed to enter its premises. About seven or eight days later Mr S.Kh. had brought home her son, Mr V.M. She had not asked him where he had been detained. On the following day Mr S.Kh. had told her that Said‑Emin Sambiyev had confessed to killing a Russian woman in Grozny. In the summer of 2004 her son, Mr V.M. had left Russia. 67.
