According to Malir SSP Rao Anwar, police raided Jamia Masjid Zakriya Kondali and recovered people whose ages ranged between 15 and 40.
The senior superintendent of police said they were drug addicts and the seminary`s administration was running a detoxification unit. A signboard at the seminary said that drug addicts were treated there.
Police said the inmates had been brought there by their families for treatment of addiction. However, keeping them in fetters was highly objectionable and illegal, the SSP said.
The caretaker of the seminary, Qari Dawood, fled, but three members of the management were detained, police said.
The place was raided after a television channel broadcast a report about the seminary, Mr Anwar said.
Several detained children told media personal at the seminary after their freedom that they used to be beaten up by the management of the seminary.
Most of the children were from Karachi while a few others were from Peshawar.
