With the breakup of Yugoslavia, a new agency State Security Service (SDB) was formed in March 1991. He served as the deputy of head Zoran Janaćković within the newly established State Security Service (SDB) of the Ministry of Internal Affairs of Serbia throughout 1991. Despite being a deputy, he was widely seen as "de facto" head of the agency. On 1 January 1992, he was appointed as the Head of the agency while the Minister of Internal Affairs was Zoran Sokolović. He stayed on that position until 26 October 1998. During that time, he also served as Assistant Minister of Internal Affairs of Serbia.
