Wartime Bosnian Serb security chief Stojan Zupljanin was
arrested and will be sent to the United Nations tribunal in The
Hague for trial on charges of war crimes, a spokesman for the
prosecutor's office said.
"Stojan Zupljanin was arrested today near Belgrade ... police and security agents took part in the operation. He should be extradited to the Hague in the next 72 hours," said Bruno Vekaric, spokesman for Serbia's special war crimes prosecutor's office.
He said Zupljanin was found at an apartment about eight km from the centre of Belgrade and will be taken to an investigative judge at the war crimes court in Belgrade before he is sent abroad.
A spokeswoman for the prosecution at the UN war crimes tribunal in the Hague confirmed his arrest.
Zupljanin, a commander in the city of Banja Luka during the 1992-95 Bosnia war, is charged with killing Muslim and Croat civilians.
He was one of four top fugitives indicted by the Hague and still at large 13 years after the war ended.
Their arrest and handover has been a condition for Serbia's advancement towards membership of the European Union.
