He said the interviews were one of the measures the police carried out at the request of the State Prosecutor's Office, under the constitutional law on cooperation with the UN court.
Mehun declined to reveal details of the interviews or say when the police questioned former justice minister and Croatian Intelligence Service chief Miroslav Separovic, former Security and Intelligence Service chief Markica Rebic, and former interior minister Ivan Jarnjak. The three were in office during the time Rajic was a fugitive.
Mehun said the police notified the State Prosecutor's Office and the Justice Ministry Department for Cooperation with International Courts about data collected in the interviews.
The Hague tribunal indicted Rajic in 1995 for the killing of at least 16 Muslim civilians in Stupni Do, Bosnia-Herzegovina, in 1993. Croatian police arrested him only in April 2003, when he was extradited to the UN court.
The tribunal's Office of the Prosecutor has suspected for years that Rajic hid in Croatia and Bosnia's Croat-Muslim entity with the help of a network of persons, some of whom were senior Croatian officials. After his arrest, Croatian media speculated that Rajic had been harboured by the police in the southern coastal city of Split and parts of Croatian security services. The Interior Ministry, however, dismissed the speculation on several occasions.
