Dozens of males have been freed in a raid on an Islamic boarding school in Katsina state, Nigeria, officials say.

Police said they had been subjected to "inhumane and degrading treatment".

Last month, more than 300 male students were freed from a similar boarding school in neighbouring Kaduna state.
