fundamental and human rights �.� national preventive mechanism against torture The visit arrangements and handling the affairs of all persons deprived of their liberty must be subject to the same criteria (2485/2018). According to the Oulu Police Department, investigation and detention responsibilities have been separated in all of its police prisons both administratively and in practice. Information about rights In accordance with the National Police Board guideline, persons deprived of liberty must be informed of their rights as well as of the daily routine in the detention facilities. Fulfilling this obligation must be recorded in the data system. The NPM noted that the police prison had not in all cases been recorded this information. Additionally, the police prison’s compliance with another guideline issued by the National Police Board requires further information. According to this guideline, persons deprived of liberty (regardless of the grounds) must immediately upon arrival in the detention facility be provided with a form stating their rights and duties, the police prison’s disciplinary regulations as well as the above-mentioned National Police Board guideline (4390/2018). On visits to police prisons in Lapland in 2017, the Deputy-Ombudsman noted that the document describing the rights and duties of persons deprived of their liberty was available in several languages, some of them quite rare, but not in Sámi. Taking the provisions of the Sámi Language Act into account, the Deputy-Ombudsman considered it justified to have the document translated to all three Sámi languages (6796/2017). The National Police Board reported having drawn up “Rights and obligations of persons deprived of their liberty” forms in Sámi. Catering The Act on the Treatment of Persons in Police Custody specifies that meals must be organised for persons deprived of their liberty, ensuring that they receive healthy, versatile and adequate nutrition. More detailed provisions on catering are provided in a Decree of the Ministry of the Interior specifying that persons deprived of their liberty for a continuous period of more than 12 hours are entitled to two meals per day. At least one of these meals must be hot. Other nourishment appropriate with regard to the time and duration of detention can also be arranged for persons deprived of their liberty. Catering at the Kuopio Police Prison. Among other things, the catering at police prisons was investigated during the NPM’s visits. The results have shown practices to vary considerably between police prisons and, for example, weekdays and weekends. In some situations, prisoners can be required to go without nourishment for too long. The Deputy-Ombudsman has taken the matter under investigation on his own initiative and requested the Ministry of the Interior to assess whether the prevailing practices and regulations in force secure the provision of the healthy, diverse and sufficient nourishment afforded by 81
