At least 21 foreign students staying without valid documents were arrested by police in an early morning raid on two madrassas in Pakistan's Punjab province, media reports said.
The madrassas reportedly belonged to Qazi Hamidullah Khan - a teacher of Taliban supreme leader Mullah Omar, the Express Tribune said.
The police carried out a raid on madrassa Mazahirul Uloom and Anwarul Uloom in Punjab's Gujranawala, the seventh largest city of Pakistan.
Officials from 30 police stations headed by the Superintendent of Police raided the seminaries.
Authorities arrested twenty-one foreign students living there without any valid documents, Geo News reported.
The nationality and the names of the foreigners could not be ascertained.
Police said that the arrested suspects were able to speak Urdu but could not speak Pashtu.
The security officers are investigating how and when these foreigners arrived in Pakistan and under which visa.
According to the law, if a person is not a Pakistani national, he cannot study in the country without official registration.
