The law enforcers said the madressah was run by Lal Masjid (Lal Mosque) cleric Maulana Abdul Aziz.
Police detained the custodian of the seminary – named Abdullah – and registered a case against him.
Police launched a raid in the seminary on a tip-off regarding suspicious activities.

In addition, Mutahidda Qaumi Movement has also got registered a FIR in Karachi against Maulana Aziz for his life threats to MQM chief Altaf Hussain through a video message.
