ELCI AND OTHERS v. TURKEY JUDGMENT 39 Mr Elçi messages for certain PKK members outside the prison. Mr Elçi sometimes brought back the replies. He had known Mr Elçi since they were teenagers. 265. As regards Şinasi Tur, all he could remember was that Mr Tur had had contacts with the PKK in the area. 266. Mr Güven confirmed his allegation that in 1992 Sabahattin Acar had brought cyanide poison into the prison in order to harm PKK opponents who were putting pressure on members' families. Mr Acar had handed over the poison to Mr Güven directly. He had no comment on the statement of another PKK confessor, Abdülhakim Bakir, who had earlier identified someone else as having brought the poison into the prison (paragraph 530 below). 267. Without recalling details, Mr Güven said that Niyazi Çem had contacted a PKK association in Bursa prison. He stated that Mehmet Selim Kurbanoğlu, Vedat Erten, Mesut Beştaş, Meral Daniş Beştaş, Nevzat Kaya and Hüsniye Ölmez had all acted as couriers between prisons and with outsiders. 268. He confirmed his allegation that Baki Demırhan had given him a knife in prison, which Mr Güven had asked Sabahattin Acar to procure. He had no comment on the earlier statement made by Abdülhakim Bakir that he had obtained the knife from someone else (paragraph 532 below). Mr Güven did not recall what had happened to the knife or the cyanide poison. Perhaps the knife had been confiscated in a later search before any harm was done. 269. Mr Güven said that he had had only one or two contacts with Arif Altinkalem who, as far as he could remember, had helped in the exchange of notes once or twice. Gazanfer Abbasioğlu and Fuat Hayri Demır had acted as couriers. 270. Mr Güven was unable to specify the content of any particular note or document which any applicant had passed on, given the voluminous material involved and the passing of years. He remembered that İmam Şahin had been an İstanbul lawyer who had visited a client at the Diyarbakır EType prison, and Mr Güven had received notes from the Bursa and Gaziantep prisons via Mr Şahin. He had no special information about the services which Mr and Mrs Şahin had rendered the PKK. He could not recall exactly when he had met Arzu Şahin. According to information he had obtained from his friends, Mr Güven considered that he could trust Mr and Mrs Şahin. 271. Mr Güven had made statements to the Public Prosecutor about all the lawyers and had repeated them before the State Security Court, perhaps in late 1994. However, he had not answered the summons to attend the applicants' State Security Court hearings out of concern for his personal safety, having made an enemy of the PKK.
