Police on Saturday arrested a man suspected of killing nine people and injuring another two in a shooting spree hours earlier in an eastern Serbian village. Nikola Radosavljevic, 38, was found at the local cemetery hours after the Friday night rampage in Jabukovac, a village near the border with Bulgaria, police said in a statement. There was no immediate explanation as to why the gunman opened fire with a hunting rifle, killing five men and four women who had been passing by on the street, police said. Another two people were seriously wounded. Police said the suspect, Radosavljevic, had recently returned to his village from Austria, where he works, and had had an argument with his wife before the incident. They gave no information about the wife. Serbian state television showed footage of the suspect, his clothes soaked in what appeared to be blood, being pushed by officers into a police van.
