A key suspect in the murder of Serbian Prime Minister Zoran Djindjic has been handed over to the Serbian authorities by Greece.
Mr Milenkovic has been taken to detention unit known as Hyatt
Dejan Milenkovic, also known as Bugsy, was arrested in Greece in July after more than 15 months on the run.
Serbian authorities believe he is linked to an organised crime network known as the Zemun clan.
Thirteen men have been charged with taking part in the killing of Mr Djindjic in March 2003.
Mr Milenkovich was arrested in the northern Greek city of Thessaloniki last July. He was unarmed, but carried a suitcase full of money.
Serbian BKTV channel reports that upon arrival to Belgrade, Mr Milenkovic was taken to a special detention unit known as Hyatt.
The chief suspect, Milorad Lukovic, surrendered to police in May last year. He has denied all charges.
