Leader of the vigilante group and two others were killed at the weekend in renewed attacks on Madaka community, Rafi Local Government Area of Niger State.
The attack is coming two weeks after the village head was kidnapped.
Sources said the bandits stormed the town on motorcycles, burning houses and shooting sporadically, and people scampered for safety.
Sources also said some people were kidnapped but the number is still unknown.
Chief of Staff to the council chairman Mohammed Mohammed said three persons were killed. One was leader of the vigilante group, Isyaku Alhassan, his son Abdulhamid and one other person whose name was still unknown as at last night. He said the bodies are yet to be recovered.
Mohammed said the village head was abducted a second time after spending over three months with kidnappers before being released.
