The senior officer allegedly shot himself dead in his residence in Apapa area of Lagos due to what a source described as depression and health challenge.
It was learnt that a service pistol, expended and live ammunition, were recovered at the scene by police detectives at the residence.
The deceased was said to have been depressed for a while over his inability to pay the school fees of his children due to scarcity of foreign exchange.
His remains have been deposited at a mortuary. He is survived by his wife who is said to be residing in Abuja and two children school abroad.
