One-month-long detention has been set for Kalinic for having used two fake passports which the police found during a search of a flat in which he lived in Zagreb, investigating judge Kresimir Devcic said on Thursday.
Kalinic, who was convicted in absentia in Serbia for the 2003 assassination of Prime Minister Zoran Djindjic, will be detained in the prison hospital in Zagreb until his recovery.
Kalinic, 36, sustained gunshot wounds in the incident which took place in Rakitje, outside Zagreb, on 8 June and was admitted to a hospital in the Croatian capital. The man who shot him, Milos Simovic, 31, was arrested by the Serbian police a few days later. Both Kalinic and Simovic, who were convicted in absentia of the Djindjic assassination, have been wanted in Serbia since 2003.
Kalinic, born in southern Croatia, has also Croatian citizenship.
