About 15 inmates were believed to have escaped from Nsukka Prison in Enugu state in a jail-break that occurred on Tuesday night.
A source at the prison who spoke on Wednesday on the condition of anonymity said the inmates broke their cells and scaled over the perimeter fence.
“The inmates carefully opened their cells and scaled the perimeter fence of the prisons.
“Before prison officials on night duty knew what was happening, about 15 inmates had escaped,” the source added.
Confirming the incident, Controller of the prison, Mr Lawrence Okonkwo, declined to give the number of inmates that escaped.
He said: “Yes there was a jail break last night in Nsukka prison but I am not in a position to say how many prisoners escaped.
“We are expecting the Enugu state Prisons Controller, Mr Isaiah Amariri, in Nsukka prison so that we brief him on what happened last night.
Meanwhile, searching has commenced for fleeing inmates as officials of the Nigeria Prisons Service were seen in parts of Nsukka and its environs.
