Belgrade media reported on Thursday that Serbia’s top civilian security agency got a new chief.

Danas and Vecernje Novosti daily quoted unnamed security services sources who said high-ranking police officer Tomislav Radovanovic had been named acting Director of the Security Information Agency (BIA).

Radovanovic headed the Internal Affairs Ministry (MUP) Special Investigation Methods Service and spent some time at the Serbian Embassy in Paris as police attache. He came to the BIA to head the agency’s technical department, Vecernje Novosti said. Radovanovic also served as chief of the Belgrade police SWAT unit. He is known to the public as the police officer who spoke out about the surveillance over President Aleksandar Vucic. He has been awarded a national medal for courage and an award by the Serbian Police Union.

Radovanovic replaces Aleksandar Vulin, a close associate of President Aleksandar Vucic, who was blacklisted by the US Treasury Department recently. Vulin is also known to have close ties to Moscow.
