A former Battalion Commanding Officer, who led the fight against Boko Haram in the North East, Major UJ Undianyede, is reported to have committed suicide.
He is understood to have killed himself less than 72 hours to the verdict of a court-martial trying him for alleged military infractions during the war.
He died on Monday on the premises of the Nigeria Defence Academy (NDA) in Kaduna, with his service pistol.
The offences listed against the deceased officer by the court-martial in the 1 Division included misappropriation of funds, abandonment of military post, insubordination, and desertion, among others.
The Major, a Course 55 Regular Officer and other members of his class, were said to be due for promotion to the rank of Lieutenant Colonel this September.
The Nigerian Army, Brig.-Gen. Onyema Nwachukwu told newsmen that he had not been briefed on the development.
However, the Public Relations Officer of the NDA, Major Bashir Jajira, dismissed the report, saying no officer of the academy was involved in suicide.
