ANGUELOVA v. BULGARIA JUDGMENT 13 had spent the afternoon and evening of 28 January 1996 with Mr Zabchekov, and also heard Dr Mihailov and Dr Ivanova. 66. Two of the police officers, Sergeant Penchev (A) and Sergeant Georgiev (F), mentioned Mr Zabchekov's ethnic origin in their oral evidence to the military investigator. A stated that when he had arrived at Beli Lom Street he had seen two persons emerging from the entrance of the building, one of whom had been “a Gypsy with a criminal record – Anguel Zabchekov”. In his statement F. referred to the applicant's son as “the Gypsy” (three times), “the arrested” (seven times) and “Zabchekov” (twice). 67. On 12 March 1996 the investigator conducted examinations of the witnesses Ms I.A., Ms I. M., C and D. His questions related solely to the number of times Mr Zabchekov had fallen to the ground during the chase on Beli Lom Street and the places where this had happened. On 18 March 1996 the investigator appointed an expert to analyse the clothes which Mr Zabchekov had been wearing on 28 and 29 January 1996. In his report of 20 March 1996 the expert stated that no traces of shoe soles could be found but explained that microscopic remains from particles from a shoe sole would not normally be left on soft fabric. 68. On 20 March 1996 the investigator conducted a reconstruction of the events during Mr Zabchekov's arrest in order to clarify the witnesses' evidence. Those taking part were Sergeant Mutafov (C), the young man who had been with him on 28 and 29 January (D), and the two persons who had observed the scene from their balconies, Ms I.A. and Ms I.M. The police officers who had arrived at Beli Lom Street after Mr Zabchekov was arrested by C did not participate in the reconstruction, which was almost exclusively concerned with the events before the arrival of the two police cars. The reconstruction was videotaped. 69. On 11 April 1996 the applicant submitted to the Varna Military Prosecutor's Office a request for the exhumation of her son's body and for the assignment of a new medical expert, stating that her son had been buried in haste and that exhumation of his body was essential. The applicant suspected that her son's ribs might have been broken. She also submitted to the investigator, Mr Atanasov, two X-ray photographs of her son's head taken several months before his death, to be used for the purpose of establishing whether his skull had been “soft” or “thin”. 70. On 17 or 18 April 1996 five medical experts were appointed to reexamine the conclusions as regards the causes of Mr Zabchekov's death. One of them, Dr Minchev, had participated in the initial group of experts. The other four were Professor Pavlov, head of the forensic department at the Medical University in Varna, Dr Kiuchukov, from the university's neurosurgery department, and Dr Dokov and Dr Radoinova, senior assistants in the forensic department of the same university. The experts were asked the following questions:
