- 32 84. The CPT recommends that the Centre's holding areas be equipped with an appropriate floor covering as well as tables and chairs, and that the possibility be explored of introducing some form of partitioning offering at least a degree of privacy. Of course, the recommendation already made in the context of Athens and Thessaloniki Police Headquarters, concerning the provision of an information leaflet to persons detained under the Aliens legislation (cf. paragraphs 59 and 71), applies equally to the new Centre. The CPT would also like to be informed whether the envisaged measures concerning outdoor exercise, visits, access to a telephone, medical care and accommodation for female detainees have now been implemented, and to receive details on whether the Centre has been operating within its envisaged capacity. 85. It should be emphasised that supervisory staff in a detention centre for aliens have a particularly difficult task. Firstly, there will obviously be problems of communication due to language barriers. Secondly, many of the persons detained in the centre will deeply resent being deprived of their liberty, given that they are not suspected of any criminal offence. Consequently, police officers assigned to supervisory duties in such a centre should be chosen carefully. Reference has already been made to the importance of police officers possessing developed interpersonal communication skills; this is particularly important in a detention centre for foreigners. Moreover, the supervisory staff should have a knowledge of the cultural backgrounds of the detainees, and at least some of the staff should possess knowledge of relevant foreign languages. The CPT recommends that the above considerations be borne in mind when assigning police officers to supervisory duties in the Holding Centre for Aliens at Athens airport. It is also recommended that the Centre's internal rules and information notices, as well as those expressions most commonly used in daily interactions between detainees and supervisory staff, be translated into various languages. 86. It should also be borne in mind that detainees might - through no fault of the Greek authorities - have to remain in the Centre for quite lengthy periods, on occasion for well over a month. Obviously, there can be no question of providing a developed programme of activities. However, the Greek authorities are invited to provide the detainees with access to radio/television and newspapers/magazines as well as with other suitable means of recreation. 87. To sum up, the CPT welcomes the initiative taken by the Greek authorities to set up the Aliens Holding Centre at Athens airport, which inter alia has relieved pressure on the detention facilities at Athens Police Headquarters. The establishment of specific centres for this category of detained person is a very positive development, provided they are properly equipped. The CPT would like to be informed whether it is envisaged to open any other centres of this kind in Greece.
