Bagana, a village of over 20,000 inhabitants, situated on the bank of River Benue and about 15 kilometres away from Abejukolo, the headquarters of Omala LGA of Kogi State, has been many times attacked by bandits and herdsmen.
More than 300 deaths had been reportedly recorded, with many villages razed.
The Divisional Police Officer of the local government, DSP John Ogbebor, confirmed the death, adding that the police had launched a manhunt for the killers.

A member of the gang was also killed.
It was gathered that the bandits, who were riding on motorcycles, carried AK-47 rifles and invaded Daja Market on Monday.
Our correspondent learnt that the hoodlums, who were acting on a tip-off, stormed the village market and went straight to the resident of a local produce merchant identified as Baira, and dispossessed him of his valuables.
