- 38 vi. other issues 78. The CPT was informed that the Greek Police Force is a strong proponent of regular inspections of hygiene in police detention facilities, including dedicated detention facilities for irregular migrants. The CPT would certainly support proposals to carry out regular inspections to police and border guard stations and to dedicated facilities for irregular migrants, as well as to coast guard detention facilities. The CPT would like to receive the comments of the Greek authorities on the above. 79. As indicated in previous CPT reports, the Committee believes that much would be gained from the improved organisation and enhanced cooperation between the main actors responsible for managing accommodation and care for irregular migrants. The Filakio special facility continues to demonstrate that when all the relevant State and local government bodies cooperate, it is possible to achieve a reasonably clean and well-maintained establishment. Clearly, other dedicated detention facilities for irregular migrants could also benefit from the more substantial involvement of the region and prefecture in their management. The CPT would like to receive the comments of the Greek authorities on this matter. 5. Conditions of detention in establishments under the Port Authorities 80. In the course of the 2009 visit, the CPT’s delegation visited the Port Authorities of Chios, Mytilini and Patras. In the CPT’s view, its standards for police and border guard stations apply equally to coast guard facilities serving a similar purpose, whether temporary or not. 81. In the Chios Port Authority building, the one cell (4.6m²) was adequate for holding persons for short periods of time, as was usually the case. However, it was not suitable for overnight detention (for example, two persons were held from 20 to 23 July 2009); anyone required to spend one night or longer in detention should be transferred to Chios Town Police Station. Irregular migrants apprehended by the Coast Guard are held in a pre-fabricated structure (40m²) with a tiled roof, consisting of three inter-connecting rooms, a toilet and a sink. Access to artificial lighting and natural light is adequate and ventilation sufficient. As a rule, irregular migrants are only held in this facility until such time as they have been processed (personal details recorded, finger-printed, medically screened at the hospital), which usually takes a few hours; thereafter, they are transferred to the special detention facility for aliens outside the town. Given the limited conditions and absence of access to outdoor exercise, every effort should be made to avoid large numbers of irregular migrants having to spend several days (Friday to Monday) in this pre-fabricated structure, as has occurred on occasion.
