- 10 E. Immediate observation under Article 8, paragraph 5, of the Convention 8. At the end of the visit, the CPT's delegation invoked Article 8, paragraph 5, of the Convention as regards the situation found in two establishments under the authority of the Ministry of Public Order, namely Kozani and Heraklion Police Headquarters. Conditions of detention in those establishments were wholly unacceptable and the delegation called upon the Greek authorities to take steps immediately to remedy the shortcomings observed. By letters of 31 October 2001 and 12 February 2002, the Greek authorities provided information on measures taken in the light of the delegation’s immediate observation and on other issues raised by the delegation at the end of the visit. These responses have been taken into account in the relevant sections of the present report.
