PP ANNUAL REPORT ON THE PERFORMANCE OF ACTIVITIES OF THE NPM N PM the basic information regarding the visited body or institution is developed, as are, if necessary, anonymous questionnaires for the persons deprived of their liberty and/or for the staff. Such a plan is based on data concerning the level of respect of human rights in the possession of the Ombudsman collected during previous visits and the work following complaints from persons deprived of their liberty, decisions of the Constitutional Court of the Republic of Croatia and the European Court of Human Rights and CPT reports.

In addition, data are collected on the number of police officers performing particular tasks and on their own training and the treatment of detainees/arrested persons, such as: - is uninterrupted rest of at least eight hours within 24 hours provided? Is this recorded, and if so, where? - is a translator/interpreter available (if an arrested person does not speak Croatian or if he/she is deaf, dumb or blind)? - what treatment is applied if the detainee/the arrested person is deprived of his/her legal capacity? - type of healthcare provision; 11
