The flood, triggered by torrential rain, overwhelmed the city's infrastructure and severely affected the prison facility. According to the official, the collapse of the prison wall allowed more than 200 prisoners to escape. "Some Boko Haram commanders held in our facility have escaped with other prisoners," the source added, speaking on condition of anonymity. 

Despite the massive breakout, authorities were able to transfer another 200 inmates to a different facility to prevent further escapes.
