A youth was killed last night in fresh violence in the strife-torn town after a lull of two days when members of two communities clashed at a place under Baradari police station, hurling brickbats and opening fire.
Police said the incident took place in Jogi Newada locality in which Imran (20) was hit by a bullet and later died at a private hospital.
District Magistrate Manish Chauhan, however, had said Imran was killed in a clash related to election rivalry. Earlier, two persons died in the clashes.
