Serbian prosecutors say that Çeku committed war crimes as a leader of the Kosovo Liberation Army during the Yugoslav wars in the 1990s.
He was Prime Minister of Kosovo from 2006 to 2008.
Twice in the past, Çeku has been arrested outside of Serbia and considered for extradition, once in Hungary and once in Slovenia. In both cases, the United Nations Interim Administration Mission in Kosovo ruled that an extradition would have no legal ground.
Franz Lothar Altmann, professor at the University of Bucharest, told RFI that he was surprised that Bulgaria arrested Çeku.
"It might be that it was local police amicable to Serbia who do not know the international implications," Altmann said.
Serbia said Wednesday that it has formally requested Çeku's extradition from Bulgaria.
