Internal Affairs Sector, existed earlier as the Inspector General’s Service (IGS) of the Department of Public Safety (DPS) within the Ministry of Interior of the Republic of Serbia. Inspector General’s Service was formally founded on 12 March 2001, when Police Code of Procedure for the Inspector General’s Service of the DPS was adopted. However, the actual process of setting up the Service did not begin until June 2003, with the naming of the first Inspector General in Ministry. The founding of the Inspector General’s Service of DPS was one of the priority tasks  within Reform Programme of the Ministry of Interior, where  the function of control  and surveillance of the police was defined as one of the key areas of this Ministry.
