At least 11 people were arrested after police busted an illegal immigration nexus in Delhi which involved Bangladeshi nationals.

Police said illegal immigrants used jungle routes and express trains to enter Indian territory.

The accused, including document forgers, Aadhaar operators, and tech experts, used a fake website, 'JANTAPRINTS.SITE,' to generate fraudulent birth certificates and other IDs, UNI news agency reported.

The racket came to light recently during the probe into the murder of Sentu Sheikh alias Raja in Delhi’s Sangam Vihar.

During the investigation of this murder, four Bangladeshi nationals—Midul Miyan alias Akash Ahmed, Fardeen Ahmed alias Abhi Ahmed, and two women were arrested, reported UNI.

The accused confessed during interrogation that Sentu Sheikh had been threatening them on various pretexts. To eliminate him, they planned his murder a month in advance. According to their plan, they strangled him and stole his cash and belongings, which were recovered during the investigation, the news agency reported.

During interrogation, all the arrested individuals shared their Bangladeshi ID cards (chip-based NID cards) or birth certificates.

Police recovered 21 Aadhaar cards, 4 voter ID cards, and 8 PAN cards suspected to belong to Bangladeshi nationals from Sentu Sheikh's residence.

"Four voter ID cards belonging to Bangladeshi nationals were recovered from Sentu Sheikh's residence. Efforts were made to trace all four individuals, and one such woman was located in Bareilly," police told UNI.

During the investigation, it was found that her voter ID card was issued using Aadhaar registered at Sentu Sheikh's address.

She shared her Bangladeshi identity documents during further questioning.

Further probe into the case is currently underway.
