-5In the above-mentioned report, the CPT also stressed that if the Greek authorities continued to fail to improve the situation in the light of the recommendations made, it may have no choice but to set in motion the procedure provided for in Article 10, paragraph 2, of the Convention3. 4. It is therefore regrettable that the Greek authorities’ response to the report on the 2005 visit failed to address many of the serious concerns identified by the Committee. This is particularly the case as regards the response to those sections of the report dealing with law enforcement agencies and prison-related issues. With a view to pursuing a constructive dialogue, the President of the CPT addressed a letter to the Greek authorities on 18 December 2006 (see Appendix II), highlighting some of the major shortcomings in the response and requesting that additional information be provided to the Committee. No reply was received to this letter4. Before taking any formal decision with regard to the Article 10, paragraph 2, procedure, the CPT felt it was best to carry out another visit to Greece in the hope of promoting a meaningful dialogue with the Greek authorities. The main purpose of the visit was to examine the steps taken by the Greek authorities to implement recommendations made by the CPT after the August/September 2005 periodic visit and to hold high-level talks with the Greek authorities with a view to enhancing their co-operation with the Committee. To this end, the delegation focused on safeguards against ill-treatment of persons detained by law enforcement officials and on conditions of detention in police stations and in holding facilities for aliens. The delegation also paid a targeted visit to Korydallos Men’s Prison in order to examine the conditions of detention in the segregation units and to assess developments in relation to the prison’s health-care service. At the end of the visit, the delegation held wide-ranging talks with senior officials from the Ministries of Justice and Public Order to discuss the response to the report on the 2005 periodic visit, and to provide feedback on the findings of the 2007 ad hoc visit. C. Establishments visited 5. The delegation visited the following places of detention: Establishments under the authority of the Ministry of Public Order Attica prefecture - Aspropyrgos Police Station - Akropolis Police Station - Kolonos Police Station - Neo Kosmos Police Station - Omonia Police Station - Palio Falio Police Station - Aghios Panteilemonos Police Station - Syntagma Police Station 3 4 Article 10, paragraph 2, reads as follows: "If the Party fails to co-operate or refuses to improve the situation in the light of the Committee's recommendations, the Committee may decide, after the Party has had an opportunity to make known its views, by a majority of two-thirds of its members to make a public statement on the matter". By letter of 5 July 2007, the CPT received some general information from the Ministry of Public Order pertaining to certain of the recommendations the Committee had made in its report on the 2005 visit to Greece.
