4. Rooms for detained persons (PDRs) 4.1. Introduction In 2016, the NMPT visited 4 rooms located within police units and assigned for placing detained persons or intoxicated persons to sober up106. There are 333 police detention rooms across the country. Over 50% of them (186) were visited by the NMPT in the period 2008–2016. The number of conducted visits made it possible to precisely identify PDRs’ main problems and reasons thereof. Thus, in 2016 the NMPT visited only a limited number of such detention rooms located within police organizational units. 4.2. Systemic problems 1. Strategy against human rights violations by police officers The Ministry of the Interior developed a  document entitled Strategy against human rights violations by police officers, which provides for conducting activities in 10 thematic areas, including: consideration of complaints against police officers, educational activities, research on police aggression, and support to victims. In the Commissioner’s opinion, it is necessary to quickly adopt appropriate systemic solutions that effectively prevent the use of violence against detainees by police officers during investigation activities (e.g. interrogation of detainees). The urgent need for such solutions is confirmed by the currently ongoing proceeding relating to suspected use of torture (beating, kicking in different parts of the body, use of a taser gun) against a man arrested by officers of the Municipal Police Headquarters in Olsztyn on charges of drug possession (the case is being investigated by the District Prosecutor’s Office in Ostrołęka; ref. no. V Ds. 91/15107), and by the NMPT visits to police rooms for detained persons or intoxicated persons to sober up, held in the period 2011–2015, which identified cases of detainees’ ill-treatment by police officers (e.g. pushing, ear pulling or slamming on the face). PDRs in: Aleksandrów Kujawski, Busko Zdrój, Płońsk and Krasnystaw. The issue is still monitored by the CHR; ref. no.: II.519.617.2015. 106 107 42
