MADRID - Spanish police arrested Vladimir Milisavljevic, one of the fugitive convicts in the 2003 assassination of Serbian prime minister Zoran Djindjic, they said on Friday. Milisavljevic, on the run after being convicted in 2007 along with 11 others for the killing, was arrested Thursday in a restaurant in the eastern city of Valencia, along with Serbian gang leader Luka Bojovic, a police statement said. Bojovic is the leader of the “Zemun Clan”, a mafia gang that developed from the “Tigers of Arkan” paramilitary group, “known for its cruelty during Balkan wars” of the 1990s, the statement said.
