6.  The applicant was born in 1976 and lives in Zakan-Yurt, the Chechen Republic. The applicant is the brother of Mr Rustam (also known as Balavdi and Khamzat) Kagirov, who was born in 1979. Mr Rustam Kagirov suffered from a disability due to removal of one of his lungs. 7.  According to the applicant, his brother had held strong religious beliefs and had studied at an “Islamic Institute” in Grozny. In the applicant’s opinion, Mr Rustam Kagirov’s religious convictions could have led the authorities to consider him a follower of Wahhabism, an Islamic fundamentalist movement, whose members had been accused of supporting illegal armed groups in the Chechen Republic. 8.  On an unspecified date in the autumn of 2004 officers from the 7th Company of the 2nd Regiment of the Chechen traffic police allegedly apprehended Mr Rustam Kagirov and tortured him for two days demanding that he confessed to involvement in illegal armed groups. The officers had suspected him of the illegal activity because of a photograph depicting two men, one of whom thought to be a leader of an illegal armed group and the other one resembled Mr Rustam Kagirov. 9.  At the time of the events described below, the Kagirov family, including the applicant and Mr Rustam Kagirov, resided at 50 Sovetskaya Street in Zakan-Yurt. Their house was situated about a hundred metres from the building of the village administration. 10.  On 17 May 2009 Mr Ramzan Kadyrov, President of the Chechen Republic, was supposed to take the Kavkaz (also referred to as the Rostov‑Baku) motorway. Therefore, a section of the route between Grozny and Zakan-Yurt was heavily guarded by traffic police officers, who were stationed at every intersection and who would not let any vehicle through without checking the drivers’ and passengers’ identity documents. Driving from Grozny to Zakan-Yurt on that day the applicant was stopped on the motorway three times for identity checks. 11.  At about 6 p.m. on that day the applicant, having pulled over to his house, saw a black VAZ Priora vehicle with registration number A 720 AT 95 parked next to the village administration in Sovetskaya Street. Meanwhile, Mr Rustam Kagirov and his friend Mr Kh.Kh., were walking in the street, next to the administration. When they were passing by the Priora vehicle, three armed men in black uniforms got out of the car. Two of them grabbed Mr Rustam Kagirov and forced him into the back seat. The third man pointed his gun at Mr Kh.Kh. and shouted in Chechen: “Turn around or I will shoot you!” Immediately thereafter the armed men got back in the car and drove off at high speed. 12.  A few moments later the applicant, accompanied by Mr Kh.Kh., got into his car to follow the abductors. They saw that the abductors had passed, unimpeded, a roadblock situated on the road leading to Zakan-Yurt from the Kavkaz motorway which was manned by several traffic police officers. Then the abductors took the Kavkaz motorway and headed in the direction of Grozny. At the roadblock the applicant asked the police officers about the identity of the persons in the Priora vehicle they had just let to pass through and whether their documents had been checked. The policemen replied that they had not checked their documents as the persons had been in a hurry. Although the applicant immediately informed them that the men in Priora car had abducted his brother, the policemen disregarded that information and continued checking other vehicles. Despite being equipped with portable radio sets and mobile phones, they took no steps to alert other policemen of the abduction or ask them to stop the abductors’ car. 13.  The applicant has had no news of Mr Rustam Kagirov since his abduction.
(b)  Information submitted by the Government 14.  The Government did not contest the basis of the applicant’s account concerning the circumstances of the abduction. At the same time they pointed out that the abduction of Mr Rustam Kagirov had taken place during “peacetime” in the absence of curfew and that unidentified armed culprits driving a civilian vehicle had been responsible for the incident. They stressed that in his initial complaints of the abduction lodged with the authorities between 18 and 21 May 2009 the applicant was not consistent in the description of its circumstances by submitting that the abduction had taken place from home, then that it had taken place from the street and then that Mr Rustam Kagirov had gone out and had not returned. They further stated that the applicant’s allegation of the increased security measures and presence of additional roadblocks on the motorway on the date of the abduction was based only on his own statement and that of Mr Kh.Kh. and that it was not unsubstantiated by any other evidence such as media reports or official announcements of enhanced security measures. 15.  The Government were invited to provide an entire copy of the case file opened into the abduction of Mr Rustam Kagirov. In response to the Court’s enquiry of 9 July 2009 they provided copies of partial contents of case file no. 74024 reflecting “only the period of investigation between 18 May and 7 December 2009”. In reply to the second request for the entire contents of the case file of 19 September 2013, the Government furnished a copy of the contents reflecting “the period of the investigation after December 2009” on 1133 pages. The relevant information can be summarised as follows. 16.  On 18 May 2009 the applicant complained of Mr Rustam Kagirov’s abduction to the Achkhoy-Martan District Prosecutor’s Office (the district prosecutor’s office) stating, amongst other things, the following:
“At about 6 p.m. on 17 May 2009 a group of armed men in camouflage uniforms stormed into our house. Threatening us with firearms, they had taken away my brother, Rustam Kagirov ...
These men did not introduce themselves and behaved rudely. They forced my brother into a black Priora model vehicle with registration number 720 and drove away with him. His whereabouts remain unknown to us ...” 17.  On 19 May 2009 the applicant’s other brother, Mr Baudin Kagirov, complained of the abduction to the Chechnya Prosecutor. He provided detailed description of the circumstances of the abduction similar to the applicant’s submission to the Court. In addition, he provided the investigators with the registration number of the abductors’ vehicle and the address of its official owner. He did not mention the abductors’ alleged passage through the roadblock. 18.  On 20 May 2009 the applicant complained to the Achkhoy-Martan District Department of the Interior (the ROVD) of Mr Rustam Kagirov’s disappearance stating, amongst other things, the following:
“I request that measures be taken to establish the whereabouts of my brother Rustam Kagirov, who on 17 May 2009 left home [situated] next to Zakan-Yurt administration and did not return ...” 19.  On the same date, 20 May 2009, a group of the ROVD police officers arrived at the applicant’s house and questioned the applicant and his relatives (see paragraphs 59-61 below). 20.  On the same date, 20 May 2009, the investigators examined the crime scene. No evidence was collected. 21.  On 19 June 2009 the Achkhoy-Martan Inter-District Investigations Department of the Prosecutor’s Office of the Russian Federation in the Chechen Republic (the investigations department) opened an investigation into the abduction of Mr Rustam Kagirov under Article 126 § 2 of the Criminal Code (aggravated kidnapping). The case was given the number 74024. 22.  On 6 July 2009 the applicant was granted victim status in the criminal case and questioned again. The applicant reiterated his previously given statement (see paragraph 59 below). 23.  On 7 July 2009 in reply to the applicant’s detailed request on the progress of the investigation, the investigators informed him that they had neither yet interviewed the traffic policemen from the Zakan-Yurt roadblock nor identified the owner of the abductors’ vehicle. 24.  On 31 July 2009 the investigators requested the Chechnya traffic police to provide information on the owner of the Priora vehicle and the identities of the traffic police officers who had manned roadblocks on the Kavkaz (Rostov-Baku) motorway on the date of the abduction:
“... you are requested to provide information concerning the traffic policemen who were on-duty on the motorway Rostov-Baku between Zakan-Yurt and Grozny at about 6 p.m. on 17 May 2009;
... information concerning the owner of the vehicle with registration number A720 AT 95/RUS ...” 25.  On an unspecified date in August 2009 the Chechnya traffic police replied to the investigators that on the date of the abduction the traffic policemen had only manned the permanent checkpoint at the entrance to Grozny:
“... On 17 May 2009, at about 6 p.m., on the motorway Kavkaz between Zakan-Yurt and Grozny, no roadblocks of the traffic police were put in place, save for the regular stationary checkpoint of the traffic police “Chernorechye” at the crossroads of the motorway Kavkaz and the entrance to Grozny ...”
The letter further provided information concerning the owner of the Priora car, Mr S.Kh. and his address. 26.  On 27 August 2009, the investigators again examined the crime scene. No evidence was collected. 27.  On 30 August 2009 the deputy head of the Chechnya Investigations Department instructed the investigators to take a number of necessary steps, including the following:
“... 4.  To identify and establish the whereabouts and question the traffic police officers who had been on-duty at about 6 p.m. on 17 May 2009 at the roadblock on the Rostov-Baku motorway between Zakan-Yurt and Grozny and find out whether they had stopped black Priora car with registration number A 720 AT 95; to show them for identification Rustam Kagirov’s photograph and establish who had been in the vehicle, how they had been dressed, whether they had been armed and whether they had shown service identification documents, and if so, to which power structure they had belonged; ... 9.  To take steps to establish whether on 17 May 2009 a special operation was carried out in Zakan-Yurt to detain Rustam Kagirov and if so, to take all measures to identify the servicemen who had been in charge of the operation and who had detained Rustam Kagirov; 10.  To take all possible measures to verify whether Rustam Kagirov was detained by servicemen from the Shatoy ROVD and taken to their premises ...” 28.  On 12 November 2009 the investigators requested that the ROVD identified the police officers who had manned the Rostov-Baku motorway on 17 May 2009. They also requested that the police verified whether a Priora vehicle, with registration number A 720 T 95 RUS, was registered as belonging to local law enforcement bodies, including the police and the Federal Security Service. From the documents submitted it follows that no reply was given to this request. 29.  On 17 November 2009 the Chechnya Ministry of the Interior informed the investigators that they had compiled photo fit pictures of the three perpetrators of Mr Rustam Kagirov’s abduction. 30.  On 18 November 2009 the investigators requested that the ROVD put up copies of the photo fits in public places. 31.  Between July and November 2009 the investigators requested a number of State authorities and detention facilities to inform them whether they had arrested or detained Mr Rustam Kagirov. No information in the positive was received. 32.  According to an information statement issued by the ROVD on an unspecified date in 2009, Mr Rustam Kagirov had participated in illegal armed groups together with another individual, Mr R.B., which was proven by a photograph of those two men together. The document also stated that “according to recent operational information, at present, having joined an illegal armed group led by Mr I.A., he [Mr Rustam Kagirov] is [hiding] in the mountains.” The sources of that information were not specified. 33.  On 19 November 2009 the investigation of the criminal case was suspended for failure to identify the perpetrators. It is unclear whether the applicant was informed thereof. 34.  On 23 November 2009 the head of the investigations department ordered that the investigation was resumed and a number of steps were taken. In particular, his written instructions contained the following orders:
“... 3.  To question the applicant and find out the reasons why in his complaint of the abduction of 18 May 2009 to the Achkhoy-Martan district prosecutor’s office he stated that Rustam Kagirov had been abducted from home whereas in the complaint lodged with the Achkhoy-Martan ROVD of 20 May 2009 he stated that Rustam Kagirov had been abducted from the street ......
... to question ROVD officers concerning the source of the information of Rustam Kagirov’s alleged membership in illegal armed groups;
... to examine the Priora vehicle with registration number A 720 T 95 and question its owner Mr M.T. in order to clarify whether he was implicated in the abduction;
... 12.  To verify the information concerning Rustam Kagirov’s apprehension by the policemen from the Shatoy district department of the interior and his subsequent detention on the premises of that police station. To question the employees of its temporary detention centre who were on-duty between 17 and 20 May 2009 and examine the centre’s registration log of detainees ...
The above investigative steps are to be taken by 30 November 2009 ...” 35.  On 7 December 2009 the investigation was resumed. 36.  On 28 December 2009, the investigators examined Mr M.T.’s Priora car. No evidence was collected. 37.  On 30 December 2009 the investigators issued a decision concerning the seizure of the detainees’ registration log of the Shatoy ROVD owing to “the information concerning the involvement of its employees in Mr Rustam Kagirov’s abduction and his detention on the ROVD premises...” 38.  On 30 December 2009 the Shatoy ROVD informed the investigators that their police station did not have either a temporary detention unit or any other types of detention cells. 39.  On the same date, 30 December 2009, the investigators examined the “registration log of persons taken to the temporary detention unit of the Shatoy ROVD (путевой журнал конвоирования задержанных лиц ИВС) between 3 May 2008 and 30 December 2009”. Mr Rustam Kagirov’s name was not indicated therein. 40.  On 11 January 2010 the ROVD informed the investigators that Mr Rustam Kagirov had participated in the illegal armed group of Mr I.Us. and that as a result of operational search measures it was established that he had not been taken to or detained in Shatoy ROVD. 41.  On 11 January 2010 the investigation was again suspended and the applicant was informed thereof. 42.  On 5 February 2010 the deputy head of the Chechnya Investigations Department ordered that the investigation be resumed for the investigators’ failure to take necessary steps. He ordered that, amongst others, the following steps were taken:
“... establishing the identity and the whereabouts of Mr Z.A. who had been sentenced by the Achkhoy-Martan district court to imprisonment and was serving the sentence and question him about the circumstances of his encounter with Rustam Kagirov [in the mountains] ...” 43.  On 5 February 2010 the investigation was resumed. 44.  On 9 February 2010 the Chechnya Department of the Federal Security Service informed the investigators that on 13 November 2009 as a result of a special operation, the illegal armed group of Mr I.Us. had been eliminated by direct hit of a high precision missile. The fragments of up to nine bodies found at the place of the impact were not susceptible to identification other than by the comparative analysis of the suspects’ DNA and that of their relatives. 45.  On 16 February 2010 Mr Z.A. was questioned (see paragraph 72 below) and participated in the photo-identification of Mr Rustam Kagirov. He did not identify Mr Rustam Kagirov as a member of the illegal armed group. 46.  On 9 March 2010 the investigation was suspended. The applicant was informed thereof. 47.  On 16 March 2010 the investigation was resumed. 48.  On 16 April 2010 the investigation was suspended again. The applicant was informed thereof. 49.  On an unspecified date in April or May 2010 the investigation was resumed. 50.  On 25 May 2010 the investigators decided to take the blood sample of the applicant’s mother Ms Z.K. for comparative examination of her DNA with the fragments of the bodies found at the place of the elimination of the illegal armed group of Mr I.Us. (see paragraph 44 above). 51.  On 26 May 2010 the investigation was suspended. The applicant was informed thereof. 52.  On 3 November 2010 the experts of the Forensics Bureau of the Stavropol Region issued their evaluation report for the investigators. According to their findings, the mother of Mr Rustam Kagirov Ms Z.K. was not related to the fragments of the bod(y)ies found (see paragraphs 44 and 50 above). 53.  On various dates between May and November 2010 the investigators requested information concerning the phone calls made from Mr Rustam Kagirov’s mobile telephone and their locations. From the documents submitted it follows that this information did not yield tangible results. 54.  On 20 February 2013 the investigation was resumed. 55.  On 20 February 2013 Ms Z.K. was informed of the results of the expert evaluation. 56.  On 20 February 2013 the investigators forwarded information requests to various law enforcement and military agencies asking to inform whether any special operations had been carried out by their agents against Mr Rustam Kagirov in May 2009 in Zakan-Yurt. No replies were given to these requests. 57.  On 21 February 2013 the investigation was again suspended. The applicant was informed thereof. 58.  The investigation in case no. 74024 is still pending. 59.  On 20 May 2009 the policemen questioned the applicant and Mr Kh.Kh. whose statements concerning the abduction were similar to the applicant’s account submitted to the Court. Neither the applicant nor Mr Kh.Kh. informed the investigators about the abductors’ unimpeded passage through the police roadblock on the motorway. Both witnesses provided detailed description of the abductors’ appearance and the registration number of their vehicle. 60.  On 20 May 2009 the investigators also questioned the applicant’s other brother, Mr Adam Kagirov, whose statement was similar to that of the applicant. However, the witness added that the abductors’ car had been stopped by the police at the roadblock and that the policemen had not checked the abductors’ identity documents and had let the vehicle pass as the latter told them that they had been police officers. 61.  On the same date, 20 May 2009, the policemen also questioned two of the applicant’s relatives, Ms Z.Kh. and Ms Z.K., whose statements were similar to that of the applicant provided on 20 May 2009. 62.  On 22 May 2009 the police again questioned Mr Kh.Kh. whose statement concerning the abduction was similar to the applicant’s account submitted to the Court. In addition, the witness stated that he and the applicant had arrived at the roadblock during their pursuit of the abductors and had asked the police officers why the latter had not stopped the abductors’ car. The officers had explained that the persons in that vehicle had been officers of a law enforcement agency in a rush and that they had not been able to tell them to which law enforcement agency the persons had belonged. According to the officers, they had not had enough time to see who had been in the vehicle. The witness provided a detailed description of physical appearance of two of the abductors. 63.  On the same date, 22 May 2009, the police again questioned the applicant’s brothers, Mr Adam Kagirov and then Mr Baudin Kagirov, whose statements were similar to the applicant’s account submitted to the Court. In addition, Mr Baudin Kagirov stated that after his brother’s abduction he had obtained access to the traffic police database and found out that registration number A 720 AT 95 of the abductors’ vehicle belonged to Mr S. Kh. The witness provided the investigators with the address of Mr S. Kh. 64.  On 6 July 2009 the investigators again questioned Mr Kh.Kh. who reiterated his previously given statements. 65.  On various dates between August and November 2009 the investigators again questioned the applicant, Mr Kh.Kh., Mr Adam Kagirov and Mr Baudin Kagirov all of whom reiterated their previously given statements (see paragraphs 59 and 62 above) . 66.  Between July and November 2009 the investigators questioned fifteen of Mr Rustam Kagirov’s neighbours and relatives, as well as owners of the Priora vehicle. The witnesses had not witnessed the abduction but had learnt of it from the applicant and his brothers. In addition, when questioned, Mr S.Kh., stated that in 2006 he had sold a Priora vehicle with the registration number A 720 AT 95 to Mr M.T. When questioned on 12 September 2009 Mr M.T. confirmed the vehicle’s purchase in 2006 but denied having any knowledge of the abduction. 67.  On various dates in December 2009 the investigators questioned several of Mr Rustam Kagirov’s former classmates and employees of the local administration next to which the abduction took place. None of the questioned persons either witnessed the abduction or had any pertinent information about it. 68.  On 28 December 2009 the investigators again questioned Mr M.T. who reiterated his previously given statement concerning the Priora vehicle and its registration number and stressed that he did not know anyone from either Zakan-Yurt or the Achkhoy-Martan district. 69.  On 30 December 2009 the investigators questioned officers of the Shatoy ROVD Mr U.A. and Mr A.I. both of whom stated that their ROVD did not have detention cells owing to repair works in the building and that the detainees were taken to the temporary detention facility of the Chechnya Ministry of the Interior. They did not recall seeing Mr Rustam Kagirov on the premises of their ROVD. 70.  On 31 December 2009 the investigators again questioned the applicant who reiterated his previously given statements and added that the difference in the abduction complaints lodged with the prosecutor’s office and the police was due to the fact that the complaint to the former had been typed by an employee of that office and that he had only signed the document without reading its contents in detail. The applicant stressed that his brother had been abducted next to the administration building which was situated close to his house. 71.  On 31 December 2009 the investigators questioned the operational search officer from the Achkhoy-Martan ROVD Mr Z.B. who stated he had been responsible for the search for Mr Rustam Kagirov. He further stated that one of the detainees taken to their police station in October 2009, Mr Z.A., had told him that he had seen Mr Rustam Kagirov next to Roshni‑Chu in the Urus-Martan district in the illegal armed group of Mr I.Us. The officer further stated that according to operational information, the abduction of Mr Rustam Kagirov had been staged by his relatives to avoid his prosecution for the membership in illegal armed groups. According to the officer, Mr Z.A. was serving a prison sentence. 72.  On 16 February 2010 the investigators questioned Mr Z.A. about his membership in the illegal armed group of Mr I.Us. The witness stated that he had spent fourteen days in the autumn of 2009 with the group. He did not see Mr Rustam Kagirov there. 73.  On 3 March 2010 the investigators again questioned the operational search officer from the Achkhoy-Martan ROVD Mr Z.B. who stated that he had received information concerning Mr Z.A.’s meeting with Mr Rustam Kagirov in the illegal armed group (see paragraph 71 above) from the head of criminal police division of the Achkhoy-Martan ROVD officer Mr A.M. 74.  On 3 March 2010 the investigators questioned Mr A.M. who stated that after his arrest Mr Z.A. had identified Mr Rustam Kagirov by photograph as one of the members of the illegal armed group whom he had met in the autumn of 2009. 75.  On various dates in March and April 2010 the investigators questioned forty-four persons all of whom stated that at some point in the past they had either sold or purchased a Priora vehicle. None of them had any information pertaining to the abduction. 76.
