When the Serbian reformist Prime Minister Zoran Đinđić was assassinated on 12 March 2003, it prompted Serbian authorities to launch Operation Sabre. Ceca's Belgrade home was raided as part of the crackdown on the network of criminals and nationalists behind the assassination. The raid led to a thorough investigation. She was arrested on 17 March 2003 and charged with illegal possession of multiple firearms. Ceca was one of dozens of people detained in the crackdown and she spent three months in prison. She claimed the firearms were brought to the house by her late husband.
