Gunmen shot a traditional chief in Sagamu, Ogun dead on Monday.
It was gathered that the three-man gang shot the chief in his head at close quarters.
He has since been buried according to Islamic rites.
Commissioner of Police in the state, Mr Abiodun Alamutu, confirmed the attack and assured that the assailants would be arrested.
“I have just returned from Sagamu. It is true. We are suspecting murder and we are on top of it.
“We are trying to unravel the mystery behind the death,’’ Alamutu said.
