Simon Belšak has been named the head of the Murska Sobota Police Directorate, succeeding Borut Kocet. Klemen Trček has been appointed to lead the Kranj Police Directorate, replacing Uroš Čadež. In Serbia, high-ranking officials Marko Kričak, head of the Criminal Police Directorate, and Boško Sekulović, head of the Crime Suppression Service, were arrested in Belgrade. The arrests were ordered by the Higher Public Prosecutor's Office and carried out by the Service for the Fight against Corruption regarding the Senjak case, which involves the May 12, 2026, murder of Aleksandar Nešović at the “27” restaurant. According to criminal complaints, Kričak and Sekulović allegedly falsified evidence, pressured witnesses, and withheld information to frame former police official Veselin Milić for the crime. The officials also face allegations of physical abuse and brutality against suspects during interrogations. Following the arrests on November 1, 2026, the High Court in Belgrade ordered detention for both suspects for up to 30 days. The Serbian Ministry of Internal Affairs has temporarily suspended both officials from work. Following the suspension of Kričak, Nevenko Marić, the former head of the Novi Sad Police Administration, has been appointed to lead the Criminal Police Administration. Marić’s appointment has faced criticism from legal professionals, including lawyer Goran Stupar, who argued that Marić is unfit to lead the unit. Critics cited Marić’s previous conviction for mobbing an inspector and prior allegations regarding the protection of a criminal during his tenure. ## Claims - Marko Kričak, head of the Criminal Police Directorate (UKP), was arrested.
