(ANSA-AFP) - BELGRADE, OCT 3 - Serbia arrested the suspected leader of a group of gunmen who killed a Kosovo police officer on September 24, the Serbian interior ministry said Tuesday. Milan Radoicic was remanded in custody for 48 hours and handed to the Belgrade public prosecutor's office, the ministry said in a statement, adding that police searched his flat and other properties. It did not say where he was arrested. Radoicic is a businessman and former Kosovo Serb politician. Formerly vice-president of the Serbian List (Srpska Lista), the main political grouping of Kosovo Serbs, he resigned from his post last week. He was questioned by Serbian police for the first time on Saturday. A few days earlier, Serbian President Aleksandar Vucic had stated that Radoicic was in "central Serbia" and available for questioning by the Serb authorities. (ANSA-AFP).
