Ambrose Alli University in Ekpoma, Edo State, was thrown into mourning Thursday, after Professor Solomon Momoh of the Institute of Education slumped and died in his office.
It was gathered that the deceased had just returned from the lecture hall when he collapsed as he was entering his office.
All efforts to revive him failed as he died before any medical attention could be arranged.
Just as the university community was mourning the death of Momoh, news came that Professor Celestina Isiramen, another lecturer in the university who was abducted by unknown gunmen last week Wednesday has regained her freedom.
The News Agency of Nigeria (NAN) reports that Isiramen was released to her family on Thursday morning amidst jubilation by family members.
Isiramen of the Religious Management and Cultural Studies Department, was abducted by unidentified gunmen while driving into her residence.
The kidnappers forcibly made her to leave her vehicle and entered theirs, taking her to an unknown destination.
NAN reports that the amount said to have been paid to secure her release could not be ascertained.
A spokesman for the university confirmed the two incidents.
