- 21 Cells should be equipped with a means of rest (e.g. a chair or bench) and persons obliged to stay overnight in custody should be provided with a clean mattress and clean blankets. The CPT calls upon the Greek authorities to comply with its longstanding recommendations that all persons detained overnight be provided with a clean mattress and (when appropriate) blankets. Further, arrangements should be made to wash/clean mattress and blankets at appropriate intervals. Cells should be kept in a satisfactory state of repair and in a clean and hygienic condition. Persons in custody should be allowed to comply with the needs of nature when necessary, in clean and decent conditions, and be offered adequate washing facilities. Toilet facilities should offer an adequate degree of privacy. Consequently, the CPT recommends that firm instructions be issued to ensure that cells and sanitary facilities used by detained persons are in a reasonable state of cleanliness, and that such persons are placed in a position to wash and, in appropriate circumstances, to change their clothes and take a shower; persons detained for an extended period should also be provided with toiletries (e.g. soap and towel, toothpaste, etc.). Further, the CPT recommends that the partitioning of in-cell lavatories be reviewed, in order to ensure that adequate privacy is offered. 37. The CPT also wishes to recall that detained persons should have ready access to drinking water and should be given food at appropriate times, including at least one full meal (i.e. something more substantial than a sandwich) every day. The delegation which carried out the 2001 visit found that, in certain establishments, food was being provided to detainees or they were given 1,000 or 2,000 Drachmas (i.e. 2.93 or 5.97 €) for food every day. However, it appeared that, in other police detention facilities, no food was provided to detainees unless they could pay for it themselves; certain detained persons were paying for the food of fellow-detainees who had no financial resources. Some of the police officers interviewed stated that they were not always in a position to provide food using public funds and contended that, on occasion, they had to pay for the food for persons in their custody. The CPT recommends that current arrangements for the provision of food to persons detained by the law enforcement agencies in Greece be reviewed and, if necessary, firm instructions be issued with a view to ensuring that such persons receive appropriate food at regular intervals (including at least one full meal every day), and that they have ready access to drinking water at all times. 38. Existing regulations in Greece make reference to some of the above-mentioned requirements: police detention facilities "must meet elementary sanitary conditions" and, more particularly, "must be of adequate size, clean, frequently disinfected and thoroughly maintained. To this end, a continuous control must be exercised and the competent police authorities shall be provided with clear instructions upon what is expected of them" (cf. inter alia, CPT/Inf (2001) 19, page 46). Further, under Article 48 of Law 2910, on the entry and residence of aliens in Greek territory, the Secretary General of each region should lay down the characteristics of detention facilities designated for immigration detainees.
