The Abolongo Correctional Centre in Oyo town in Oyo State was on Friday invaded by gunmen.
It was learnt that the gunmen attacked the facility with explosives around 10.30pm and set the inmates free.
A search by security operatives for the fleeing inmates has begun.
The Public Relations Officer of the Oyo State Command of Nigerian Correctional Services, Lanre Anjonrin, confirmed the attack, saying, “I am there now and we are assessing the level of damage done. We will make our findings known later.”
It was further learnt that the attack left the facility in disarray with warders scampering for safety.
As of the time of filing this report, other security agencies have been mobilised to support men and women of the Nigerian Correctional Service in tracking down the fleeing gunmen and rearresting the prisoners.
