A former Bosnian Serb paramilitary leader has been transferred to The Hague tribunal's detention unit after giving himself up to face charges.
Jankovic is accused of torturing and raping detainees
Gojko Jankovic, 50, surrendered to Bosnian Serb authorities on Sunday.
He was a deputy commander of the military police and one of the main paramilitary leaders in Foca, south-east of Sarajevo, during the war.
The indictment says Mr Jankovic and his soldiers tortured Muslim detainees and raped a number of women.
He left Banja Luka on a flight to the Netherlands on Monday and was taken to the detention unit of the International Criminal Tribunal for the former Yugoslavia.
A date for his first appearance before the tribunal has not been set.
Mr Jankovic is the fifth Bosnian Serb to give himself up since January this year.
The government of neighbouring Serbia hailed the decision which was "is in the interests of Serbia-Montenegro and the [Bosnian] Serb Republic".
Serbia has been anxious to show that it is making progress towards fulfilling its obligations to the tribunal before the European Union decides whether the country is eligible for membership, says the BBC's Matt Prodger.
Both Serbia and Croatia have been under renewed pressure since Kosovo's former Prime Minister, Ramush Haradinaj, won international praise for his immediate surrender when he was indicted last Tuesday.
Our correspondent says Serbia's record is poor. More than a dozen indictees are still thought to be on Serbian soil.
The tribunal's top two suspects - former Bosnian Serb leader Radovan Karadzic and his military commander Ratko Mladic - remain at large.
