&37*HQHUDO5HSRUW The use of surgical castration in the context of the treatment of sex offenders was explored in the course of the visits to the Czech Republic and Germany. As the CPT has already made clear1, it is firmly opposed to the application of this intervention in that context. $GKRFYLVLWV 4. The three ad hoc visits carried out by the CPT during the period covered by this General Report were to Albania, Greece and the North Caucasian region of the Russian Federation. 5. The main objective of the ad hoc visit to Albania at the end of January 2011 was to examine the treatment of persons who had been taken into custody following violent disturbances that had occurred in Tirana earlier that month. The CPT’s delegation interviewed in private all the persons still in detention (some 35 in total) and examined relevant records at Prisons Nos. 303 and 313 and at several police establishments in the capital. The delegation also held consultations with the Minister of the Interior, the Director General of the State Police and the Prosecutor General. 6. During the ad hoc visit to Greece in January 2011, the CPT’s delegation examined the treatment of migrants held in aliens detention centres, particularly in the Attica and Evros regions, as well as the situation in several prisons. The visit had been preceded, some 12 months earlier, by high-level talks with the Greek authorities, which were focused on the need to improve the conditions of detention of irregular migrants and address long-standing problems in the prison system2. From the findings made in the course of the visit, the CPT could only conclude that effective action had not been taken to improve the situation notwithstanding the recommendations it had made after several visits organised during the previous six years. As a result, the Committee made a public statement on 15 March 2011, the text of which is reproduced in Appendix 8. As is made clear in the public statement, the CPT remains committed to continuing its dialogue with the Greek authorities, and that dialogue is being pursued on the basis of the Committee’s report on its visit in January 2011. 1. 2.
