4.  The applicant was born in 1982 and lives in Kharkiv. 5.  According to the applicant, on 31 January 2009 she was arrested by a group of police officers in a café, K., and detained without record at a police station until 2 February 2009. She further alleged that during her detention, she was beaten and threatened by the police officers, notably A.A., who tried to obtain false confessions from her concerning her and other persons’ involvement in drug dealing. According to the applicant, she did not seek any medical assistance upon her release because she intended to file an ill‑treatment complaint and expected to be instructed by the prosecutor’s office on how to document the injuries properly. 6.  According to the Government, on 31 January 2009 the police officers seized some heroin from the applicant, which was the basis for the institution of criminal proceedings against her and her eventual committal for trial. However, the applicant was neither arrested, nor detained by the police at that time. 7.  On 10 February 2009 the applicant complained about the incident to the prosecutor’s office. 8.  On 17 April 2009 this complaint was rejected as unsubstantiated. 9.  On 31 March 2010 Kyivskyy District Court in Kharkiv, which examined the criminal case against the applicant, ordered the prosecutor’s office to inquire into her ill-treatment complaint lodged again during the trial. 10.  On 23 April 2010 the Kyivskyy District Prosecutor’s Office in Kharkiv decided not to institute criminal proceedings in relation to the applicant’s ill-treatment allegations. As appears from that document, the applicant had stated to the prosecutorial authority that she and V.J. (her partner) had been arrested on 29 January 2009 and that she had been ill‑treated by police officers and detained without record until 31 January 2009. V.J., questioned by the prosecutor’s office in connection with the inquiry into the applicant’s complaints, had likewise alleged that both of them had been arrested on 29 January 2009 and that the applicant had been subsequently detained until 31 January 2009. 11.  The applicant appealed against this decision to the General Prosecutor’s Office, which forwarded the case-file materials back to the local prosecutor’s office with a view for them to be joined to the criminal investigation of the applicant’s complaint concerning the second ill‑treatment episode (see below). 12.  According to the applicant, on 18 June 2010 the Kyivskyy District Court in Kharkiv, to which the criminal case against her had been referred for examination, returned it for additional investigation. 13.  There is no further information concerning the final outcome or present status of the aforementioned case against the applicant. 14.  At 9.42 p.m. on 25 June 2009 the applicant sought medical aid at Kharkiv City Clinical Hospital no. 4. 15.  At 10 p.m. on the same date she was examined by a medical professional in that hospital and diagnosed as suffering from concussion and chest, stomach, and knee-joint contusions. She refused to be admitted as an inpatient for treatment, which was recommended to her, and left the hospital. 16.  On 26 June 2009 a new set of criminal proceedings was instituted against the applicant on suspicion of selling opium to three men on 24 June 2009 and of storing a jar of opium in her house (“the second set of criminal proceedings”). 17.  On the same date the applicant complained to the Kharkiv Regional Department of the Interior that she had been ill-treated by the police. She submitted, in particular, that on 24 June 2009 four police officers had forced their way into her house without a court order, searching for drugs. Officer A.A. had hit the applicant on the head with the grip of his gun and had struck her several times in the face with his hand in the presence of the applicant’s two-year-old son, her partner, brother, and two guests. The police officers had then taken the applicant to the police station, where she had been held from about 2 p.m. on 24 June until 5.30 p.m. on 25 June 2009 without a formal arrest record being drawn up. During that period, officer A.A. had demanded that she confess to dealing drugs under the protection of another police officer, Y.B. As the applicant had protested, he had threatened and punched her on various parts of her body. She had been released at about 5.30 p.m. on 25 June 2009 after confessing to drug-related offences and signing various documents at the demand of A.A. 18.  According to the applicant, during her visit to the Department of the Interior, she had felt so unwell that an ambulance had been called and she had been admitted as an urgent case to Hospital no. 4. 19.  According to the Government, it could be seen from the hospital records that no ambulance had been called for the applicant and she had arrived at the hospital on her own. They submitted hospital records, according to which the applicant had come to the hospital on her own from her home and was registered by the reception desk at 9.27 p.m. It can also be seen from those records that between 26 June and 20 July 2009 the applicant received inpatient treatment for a moderately serious case of concussion, accompanied by a traumatic subarachnoid haemorrhage, epileptic syndrome and several other neurological conditions. 20.  On 15 July 2009 a medical expert, having examined the applicant, reported that she had bruises on her right leg and left hip, which could be classified as minor injuries and which could have been sustained between seven and fifteen days prior to the assessment. He further concluded that he was not competent to decide on the cerebral trauma, in particular, as he had not been provided with a comprehensive medical record. 21.  On 27 July 2009 another medical expert, after examining the applicant and various medical records, concluded that the applicant’s cerebral trauma could be classified as a moderately serious injury. He further reported that the trauma could have been sustained in the circumstances described by the applicant. 22.  In July 2009 the Kharkiv Regional Department of the Interior carried out an internal investigation into the applicant’s ill-treatment complaints. 23.  On 10 August 2009 a report summarising the results of the investigation was transferred to the Kharkiv city prosecutor’s office for review and follow-up. According to the findings contained in the report there were, in particular, irregularities in the visitors’ log and other police records, making it difficult to determine the exact time of the applicant’s presence in the police station on 24 and 25 June 2009. 24.  On an unspecified date the prosecutor’s office began a preliminary investigation into the applicant’s complaints, in the course of which a number of people were questioned as potential witnesses, including the police officers implicated by the applicant in her ill-treatment, the lay witnesses, who had signed the police report concerning seizure of opium from the applicant on 24 June 2009, the three men implicated in buying opium from the applicant, the applicant’s partner, brother, guests, and the applicant herself. 25.  During the questionings, the four police officers implicated by the applicant in the forced entry to her house and ill-treating her, denied this accusation. They maintained that the applicant had willingly allowed them to inspect her house after they had caught her selling opium to three men at the entrance. In the presence of two lay witnesses, syringes full of opium had been seized from the men on the spot and a jar filled with opium had been seized from the applicant’s garage following a search of her house. In connection with those seizures, the applicant had subsequently been taken in for questioning and had been at the police station on 24 and 25 June 2009, however, she had neither been arrested, nor held there overnight. The officers also submitted that it was known to them that the applicant sold drugs under the protection of police officer Y.B. 26.  Two men identified as the lay witnesses gave statements largely consistent with the police officers’ submissions. 27.  The three men identified by the police officers as the drug buyers denied buying any opium from the applicant and submitted that they had visited her that day to borrow some money. Later on, they had been arbitrarily caught by the police and made to write false confessions, admitting that they had bought opium from the applicant, on pain of criminal sanctions. 28.  The applicant herself, V.J. (her partner), A.B. (her brother), and two persons identified by the applicant as the guests present during the purported forced entry, gave statements similar to the ones the applicant had provided to the Department of the Interior on 26 June 2009. The applicant also submitted that there had been no lay witnesses present during the forced entry and search and that the jar and syringes with opium had been brought by the police officers and planted on her. 29.  On 18 September 2009 the Kharkiv city prosecutor’s office instituted criminal proceedings against “a group of unidentified police officers” suspected of abuse of authority accompanied by violence and the use of arms against the applicant on 24 June 2009. 30.  On 22 September 2009 the applicant joined those proceedings as an aggrieved party. 31.  On 1 March 2010, responding to a request from the applicant to be updated on the proceedings and to consult the case file, the Kharkiv city prosecutor’s office informed her that the investigation was in progress and that she would be able to consult the file after it had been completed. 32.  On 9 March 2010 a further medical report on the applicant was obtained, which stated that it was not possible to determine the gravity of her cerebral trauma, in particular because of the unavailability of her previous complete medical history. It also concluded that it was unlikely that the applicant’s injuries had been self-inflicted. 33.  On 8 December 2010 A.A. was indicted within the framework of the criminal proceedings concerning the applicant’s alleged ill-treatment. The three other police officers implicated by the applicant in assisting him on 24 June 2009 were referenced in the bill of indictment by name. 34.  On 9 December 2010 the investigator S. discontinued the second set of criminal proceedings against the applicant for want of any evidence that she had stored opium in her house or had sold it to anyone on 24 June 2009. In his decision, the investigator referred to various procedural irregularities in the collection of evidence by the police officers and discrepancies in the statements of the various persons questioned as witnesses, which he deemed irreconcilable. He further decided to transfer the file of the case against the applicant to the Kharkiv prosecutor’s office in order for it to be joined to the case concerning the applicant’s alleged ill-treatment. 35.  On 21 January 2011 a further medical report was obtained. It stated that it was not possible to determine the severity of the applicant’s cerebral injury because the medical history that had been provided to the expert writing the report had been incomplete, and because the applicant herself had not reported for an examination in person. It was also noted that, as regards the bruises which had been documented in July 2009, they could have been inflicted on the dates and in the manner reported by the applicant. 36.  On 11 August 2011 a further medical report, this time by a panel of three experts, was obtained, wherein the applicant’s cerebral trauma was classified as a minor injury, which could possibly have been sustained on 24 June 2009 and was unlikely to have been self-inflicted. It was further reported that the data concerning the other injuries (bruises and contusions) were inconclusive, but that based on the available information it was not improbable that the injuries had been self-inflicted. 37.  On 29 August 2011 the Kharkiv prosecutor withdrew the bill of indictment against officer A.A., noting that the three men earlier identified as the drug buyers and one of the two people identified as the applicant’s guests who had been present during the purported forced entry had retracted their testimony incriminating A.A. and his colleagues in the assault. 38.  On an unspecified date officer M.O., one of the four officers implicated by the applicant in the forced entry, appealed to the Kyivskyy District Court in Kharkiv, seeking the annulment of the decision to institute criminal proceedings. 39.  On 12 September 2011 the Kyivskyy District Court of Kharkiv allowed the appeal, referring the case for further preliminary inquiry. The court noted, in particular, that as the applicant’s complaint had been lodged against four named police officers, it had been wrong to institute proceedings into alleged abuse of office by a group of “unidentified officers”. Furthermore, while officer M.O. had de facto been implicated in the bill of indictment against officer A.A. as his accomplice, he had been given witness status only, which had restricted his procedural rights, including the right to defence. 40.  On various dates in September 2011 formal confrontations were organised between the applicant, two of the three men identified by the police as the “drug buyers”, and a woman identified by the applicant as one of her guests on 24 June 2009. During those confrontations, the applicant confirmed her previous testimony, while the other people maintained that because they had been regular clients of the applicant’s for drugs in 2009, they had earlier given statements in her favour for fear of reprisals from her and officer Y.B., who had protected her. In fact, the two men confirmed that they had bought opium from the applicant on 24 June 2009, while the woman maintained that she had not visited the applicant on that date and had not witnessed any forced entry by the police. 41.  V.J. (the applicant’s former partner) and A.B. (her brother), also questioned again in September 2011, confirmed their previous statements that they had witnessed a forced entry and assault on the applicant. Based on the case file, the second guest (the fourth person, who had earlier contended that he had witnessed the forced entry), was not questioned. 42.  On 26 November 2011 the Kharkiv prosecutor’s office refused to reopen the criminal investigation into the applicant’s ill-treatment complaints for want of any evidence that the police officers had committed a crime. They referred, in particular, to the retraction of several witness statements and to the re-classification of the applicant’s injuries as minor in the latest medical report. They further pointed out that, according to the experts’ findings, all of the applicant’s external injuries could technically have been self-inflicted. Accordingly, she could have lied to the police about her ill‑treatment to avoid charges of drug dealing. 43.  It appears that the applicant was not informed of the above decision in due time, as in 2012 the applicant’s lawyers unsuccessfully contacted the law-enforcement authorities to obtain information on whether there had been any progress in the proceedings.
