Nigeria's president on Tuesday ordered a crackdown on abuse at Islamic schools, after a second
police raid in less than a month revealed men and boys subjected to beatings, abuse and squalid conditions.
Nearly 300 had been held captive at a school in the Daura area of Katsina, the hometown of President Muhammadu Buhari, where police said they discovered "inhuman and degrading treatment" following a raid on Monday to free the remaining students.
The 67 inmates who were freed by Katsina police were shackled, and many were taken to hospital for treatment, police superintendent Isah Gambo told Reuters.
