Cleanliness of rooms We proposed that PS Ljubljana Bežigrad regularly clean the smaller room intended for interviews and receiving clients. The MNZ replied that the additional smaller room for interviews had been cleaned immediately, and the police officers had been informed that they have to clean the room after interviewing clients (if the cleaner is not present). Both cleaners were also informed that the relevant room had to be cleaned. We proposed that PS Maribor I examine the functioning of the ventilation system in all detention rooms. If the source of unpleasant odours cannot be attributed to the ventilation system, the staff at the station should consider more effective ventilation of the room during detention. The MNZ replied that they had prepared a public procurement for the inspection of the ventilation system. Until its implementation, the police officers would more thoroughly air the detention rooms. We proposed that PS Ptuj examine and if necessary clean the interview rooms after each use. The MNZ replied that the station had been informed about our proposal. We proposed that PS Vrhnika occasionally flush the toilet in the detention room, which otherwise emits an unpleasant odour. The MNZ replied that the police officers would air the room more frequently and occasionally flush the toilet. Audio and video surveillance When visiting PS Brežice, we determined that the reception room for detained persons was still not under video surveillance; we thus proposed examining the possibility of installing video surveillance in all rooms at the station where detained persons are processed. The MNZ replied that the installation of a video surveillance system in the reception room for detained persons was anticipated in September 2016. We again proposed that PS Celje examine the possibility of installing video surveillance in the hallway and the small office in front of the detention rooms during renovation works. The MNZ responded that the hallway and office would be equipped with a video surveillance system if the upgrade of the existing system is possible and funds available for this purpose. Furthermore, we proposed that PS Celje examine the possibility of installing video surveillance in detention rooms (no. 17 and no. 16) within the renovation plans. The MNZ responded that both rooms would be equipped with video surveillance cameras if this was permitted by the existing system and if sufficient funds were ensured. We proposed to PS Domžale that the interview room be equipped with a video surveillance system or that the station receive equipment for audio and video recording of interviews. The MNZ responded that the installation of additional cameras was not anticipated at the time, and that the station had the equipment for audio and video recording of interviews.
