The Plateau Command of the Nigerian Correctional Service (NCoS) has confirmed the escape of four inmates from the Jos Custodial Centre.
Samuel Aguda, the Controller- in-Charge of the command, confirmed the development to reporters on Friday in Jos.
Mr Aguda, who said the incident occurred in the wee hours of Thursday, attributed the development to negligence on the part of personnel on duty.
He said he realised that either there is duplicate key to the cell or there was serious negligence on the part of personnel on duty, because the inmates escaped through the fence.
The controller said that it had commenced investigation to unravel the remote and immediate cause of the incident.
Currently, the Assistant Controller General in charge of Operations is personally on ground investigating the matter.
Mr Aguda called on Plateau residents to avail the Service information that would lead to arrest of the escaped prisoners.
He also assured that any officer and personnel of the Service that is found wanting in the incident would be punished.
He said the personnel on duty on the day the incident occurred had been detained within the prison yard pending the conclusion of investigation.
