Mr Humphrey Chukwuedo, NPS, FCT Command Public Relations Officer, disclosed this in a statement on Friday in Abuja.

“No one was hurt as neither the medical staff nor inmates were around the building as at the time of the incident,” he said.
Chukwuedo said that the cause of the fire was not immediately known but that the smoke may have emanated from a faulty electrical equipment in an adjoining building.
He said that the equipment was used for teaching inmates hand works.

He said that normalcy has been restored and that the prison yard is calm and peaceful.
