Nigerian police have freed more than 300 men and boys from an Islamic school in the northern city of Kaduna, with seven staff members arrested.
Many of the students had been abused and held in chains.
Nigerian police said Friday they had found and freed more than 300 men and boys from a school in the northern city of Kaduna. Many of them reported being tortured and sexually abused, and about 100 were found chained in one of the school buildings.
“We found around 100 students including children as young as nine, in chains stuffed in a small room all in the name of reforming them and making them responsible persons,” police spokesman Yakubu Sabo told the AFP news agency.
The Islamic school specialized in children who were suffering from drug-related issues and similar problems. The parents were apparently not allowed inside the premises, and instead were meeting students outside.
Most of the children came from northern Nigeria, although authorities identified two from Burkina Faso.
Police had been alerted by complaints from local residents. Sabo said seven people had been arrested, including the proprietor and six teachers.
He also said they had found a “torture chamber” where children had been chained, hung, and beaten.
Nigerian media quoted one of the students, Bello Hamza, who said he had spent three months in the school with “chains on my legs.”
“This is supposed to be an Islamic center, but trying to run away from here attracts severe punishment; they tie people and hang them to the ceiling for that.”
Nigeria has roughly even proportions of citizens following the Islamic and Christian faiths, with Islamic schools common across the mostly Muslim north.
