Three hundred persons chained together in Rigasa, Igabi Local Government Area of Kaduna State have been rescued by police officers.
The 300 which included children were rescued following a raid at a home allegedly used as an Islamic Centre.
According to the police, the victims are from Burkina Faso, Mali and other African countries.
Channels Television gathered that adults were subjected to daily recitation of the Holy Quran and prayers, allegedly accompanied by torture.
There are also claims that some of the children had been sexually abused.
While the man who runs the home claims that parents brought their children to the home for rehabilitation, the children with chains on their legs and scars of injuries from torture on their bodies, say they are forcefully subjected to daily recitation of the Holy Quran. They added that, to them, the bursting of the building by the police is liberation from slavery.
The Proprietor of the centre, however, denied the allegations of molestation and homosexuality as totally false, saying that all they do in the centre is to teach people Islam.
He also claims that those in chains are the stubborn ones who attempt to run away.
Meanwhile, the Kaduna State commissioner of police, Ali Janga told journalists that preliminary investigation reveals that the place is neither a rehabilitation centre nor an Islamic school.
He assured that the command will get to the root of the matter to ascertain the real motive behind the centre.
The rescued children have been evacuated from the premises to the Kaduna Police command headquarters for proper profiling, while an investigation continues on the mode of operations of the suspects and their motive for setting up the centre.
Rigasa, an agrarian community in Igabi local government area of Kaduna State, apart from being the most densely populated community in the state, is also predominantly inhabited by Muslims.
