On Tuesday the police in Oyo state detonated a bomb at the Medium Security Custodial Centre, Oyo.
The bomb was said to be one of the explosives planted during the deadly attack unleashed on the facility on Friday night.
Officers of the custodial centre were said to have discovered the bomb and they invited the Bomb Disposal Unit of the Nigeria Police to detonate the material.
Public Relations Officer of the Nigerian Correctional Centre in the state, Olanrewaju Anjorin confirmed the development.
The PRO said, “It is true that a bomb was detonated at the custodial centre in Oyo today (Tuesday). But the bomb disposal unit of the police was responsible for the detonation of the material.
“Our officers discovered that there was an explosive planted outside the facility and the police were invited. So, no cause for alarm.”
Hoodlums had on Friday night invaded the prison with explosive devices and guns.
While some of the inmates who escaped had returned voluntarily, some others were re-arrested and brought back by security agents.
