Hired assassins on Monday night stormed the residence of Professor Godswill Obioma, strangled him dead, Mouthpiece NGR reports.
His wife, Elizabeth Obioma told newsmen on phone on Tuesday morning that the suspected assassins took nothing away after killing him.
She said: “The assassins came in and killed him and left without taking anything.”
Weeping profusely, Mrs Obioma said her husband had just returned to Minna from a trip to Abuja when the armed men, lurking in his compound, descended on him and strangled him.
A police spokesman did not immediately return a request seeking comments about the development.
Mr Obioma has been facing attempts to remove him from office as the head of NECO, a prominent examination body run by the Nigerian government.
Mr Obioma, 67, was appointed head of NECO barely a year ago on May 14, 2020.
He hailed from Abia in Nigeria’s Igbo-dominated South-East region.
The incident came barely a day after Ahmed Gulak, a top politician of the ruling APC, was gunned down in Owerri, raising widespread fears of insecurity.
