Gurugram: Fifteen Bangladeshi nationals, including a woman, were detained in Gurugram for allegedly illegally entering the country through waterways, border fencing and pipelines in West Bengal with the help of agents, police said on Sunday.

The Bangladeshi nationals, who were allegedly residing illegally in the city, were sent to the Manesar Detention Centre, police said.

According to police, the operation was conducted in the Bajghera area by the PO Staff, Gurugram, on the basis of confidential information and after a thorough investigation.

A police team led by Sub-Inspector Rohit, in charge of PO Staff Headquarters, carried out the operation in view of the Centre's guidelines and national security concerns.

"During the investigation, it was found that all 15 individuals taken into custody, including one woman, owned identity cards and other documents related to Bangladesh. Preliminary investigation revealed that they did not possess valid visas, passports or any other requisite authorisation to stay in India," a Gurugram police spokesperson said.

The individuals had allegedly entered India through various routes with the assistance of agents. They reportedly crossed waterways, border fencing and pipelines in West Bengal before reaching Gurugram, where they had been residing illegally, the spokesperson said.

A senior police officer said all 15 Bangladeshi nationals had been sent to the detention centre in Manesar. Further legal proceedings are being carried out against them as per the prescribed procedure, he added.

A day earlier, the Anti-Terrorist Squad (ATS), Gurugram, had detained 14 Bangladeshi nationals allegedly living illegally in India during a joint operation involving the Special Operations Group (SOG) units of Nuh and Rohtak, police said.
