ANNUAL SPECIAL REPORT 2016 15 selves. The cells in question do not have a yard area and therefore it is deemed unsuitable for the administrative detention of third-country nationals awaiting return, as it does not meet the provisions of Article 31, Law 3907/2011. The guarding of the cells by the outer gate police guards was deemed unsafe for the security of both the building and the detainees and the NPM recommended the assignment of a separate guard for the holding cells. ρρ On the same date, the NPM carried out a no–notice on–site inspection of the Amaroussion (Attica) Police Station, in order to determine the conditions and procedures of administrative detention of third–country nationals and the treatment of any minors. On the day of the on–site inspection no administrative detainees were found. The existing cell has room for only a small number of persons, does not allow for the separation of administrative detainees and criminal prisoners and lacks any possibility of outdoor access, and therefore was deemed unsuitable for detention for longer than a few hours. ρρ Upon visiting the Lesvos Police Station cells the conditions were deemed bad. The detention area consists of 4 cells, parallel to each other, which open onto a narrow corridor that possesses the facility’s only windows, with the result that there is very little natural light. Adjacent to the entrance are the toilets and showers, which were particularly dirty. The prisoners move between their cells and the common corridor. The cells are narrow and without beds. There are mattresses on the floor but no sheets. The NPM recommends: ϭϭ Taking measures regarding the cleaning of the premises and particularly of the showers and toilets. ϭϭ Ensuring the prisoners are granted yard time in an outdoor space. ϭϭ Providing prisoners with sheets. Administrative detention of third–country nationals The administrative detention of third-country nationals is an issue of special concern to the NPM, particularly regarding the legality and the conditions of detention and especially in the present circumstances, which necessitate the management of a large number of refugees and migrant flows. The Greek Ombudsman’s overall picture for 2016 regarding the State’s management of the issue is documented in its special and annual reports: ρρ “Returns of third-country nationals” Special Report 2016 https://www. synigoros.gr/resources/eidikiekthesiepistrofesallodapwn2016gr--2.pdf.
