The Delhi Police has recently apprehended 36 “illegal” Bangladeshi nationals from south Delhi’s Bharat Nagar, said an official on Monday. The police have also initiated the deportation process.

The immigrants, including 19 adults and 17 children, were detained on June 13.

According to the police, they were living without valid documents, visas or permits in violation of the Foreigners Act, of 1946.

“It is during the interrogation that one of the detainees confessed that they had entered India from Bangladesh via land and then helped us identify the rest of the people illegally living in the area,” said a senior official.

“Thirteen identity cards of the Bangladeshi nationals and seven mobile phones loaded with the banned IMO app, often used for cross-border communication, were recovered from their possession,” said DCP (North West) Bhisham Singh.
