- 18 28. It should be added that, of all the above-mentioned establishments, only Khania Police Headquarters had an outdoor exercise area, to which detained persons had generous access. The CPT is particularly concerned to note that brand new premises do not include an outdoor exercise area. This was for example the case at Athens Airport Police Station, where two persons had been detained for several weeks without being offered out-of-cell time. 29. The delegation also visited the accommodation arranged by the Igoumenitsa Police Headquarters for foreigners recently rescued from a vessel adrift in international waters. Tents and mobile sanitation had been provided to them at the Drepanos Camping site, and they also had access to the site's facilities. They were allowed to move freely within a given perimeter. The situation was acceptable and the foreigners concerned were quite grateful for those arrangements. ii. transfer centres 30. The situation in the two transfer centres visited was similar to that described in previous visit reports. The Athens Transfer Centre had been repainted and the sanitary facilities tiled. However, it had otherwise not been improved in the light of the CPT's recommendations (cf. for example, CPT/Inf (2001) 18, Part II, paragraphs 38 and 39). In particular, the delegation which carried out the 2001 visit found that: the official capacity had not been reduced and that, on occasion, that capacity was exceeded (e.g. occupancy in September 2001 had peaked at 56, for a capacity of 40); although mattresses and blankets were available, the state of cleanliness of some of the items which were being provided to inmates was not satisfactory; part of the detention areas and of the sanitary facilities were in a poor state of hygiene; there was no hot water supply; and there were no outdoor exercise facilities. Following its first visit to Piraeus Transfer Centre (in 1993), the CPT recommended that, if extensive renovation of the facility was not possible, it be withdrawn from service/relocated (cf. CPT/Inf (94) 20, paragraph 77). The Greek authorities indicated that they favoured the centre’s relocation. However, the Committee has noted with concern that, despite its repeated recommendations (cf. CPT/Inf (2001) 18, Part I, paragraph 29 and CPT/Inf (2001) 18, Part II, paragraph 37), Piraeus Transfer Centre remains in its original location, unchanged. iii. border guard posts 31. Conditions at Kristalopigi and Mesopotamia Border Guard Posts for holding immigration detainees subject to immediate readmission procedures (i.e. for periods of one or two days) were far from ideal. The registers showed that, on occasion, the posts' cells could be severely overcrowded (e.g. 23 m² cells had on occasion been used to accommodate twenty or more persons overnight). Persons held overnight in those establishments were not systematically provided with mattresses and blankets, and the premises' state of cleanliness was not satisfactory. Further, at Kristalopigi, artificial lighting was poor.
