Serbian ex-police general Sreten Lukic will surrender to the UN war crimes tribunal in The Hague to face charges over alleged atrocities in Kosovo.
Sreten Lukic is among four generals accused of Kosovo crimes
Mr Lukic, who headed the heavily armed MUP paramilitary force, was indicted in 2003 in connection with killings of Kosovo Albanian civilians in 1999.
He was among four Serbian generals who allegedly planned and ordered the murders of civilians by Serb troops.
At the time Serbian forces were battling ethnic Albanian guerrillas.
Mr Lukic underwent heart surgery in October and again in March.
In February another one of the four, Serbian army general Vladimir Lazarevic, surrendered to the tribunal.
Army generals Nebojsa Pavkovic and Vlastimir Djordjevic are also wanted in connection with the Kosovo campaign.
Mr Djordjevic fled to Russia in 2001 and Mr Pavkovic has said he would rather die than surrender to the tribunal.
Angered by Belgrade's perceived reluctance to hand over suspects, the United States has suspended financial and political aid to Serbia.
The European Union has made it clear that the development of closer EU-Serbia ties depends on Belgrade extraditing wanted war crimes suspects.
