Months after the Delhi Police began probing a syndicate allegedly involved in facilitating the infiltration of illegal Bangladeshi immigrants into the country, the case was transferred to the National Investigation Agency (NIA) last week to investigate its wider network, The Indian Express has learnt.
A case under the sections relating to criminal conspiracy – referred to as the “mother conspiracy” – was registered by the Delhi Police Special Cell last April.

So far, the Special Cell has arrested over a dozen people in the case, including those allegedly involved in helping immigrants cross the border and providing them with fake Aadhaar and voter ID cards.
According to sources, Delhi Police has found that multiple network channels were operating from the border states of India. Following this, sections related to forgery and the Foreigners Act were added to the “mother conspiracy” FIR.
The Delhi Police then wrote to its counterparts in other states, sharing leads, which helped police in those states to also arrest several people.

Now, the NIA has taken over the case to unearth the entire syndicate and trace the money trail, sources said, adding that the NIA may register a new FIR in the matter.
On the directions of the Union Home Ministry, Delhi Police had launched a massive drive to identify illegal Bangladeshi immigrants in the run-up to the Assembly elections in the Capital last year. The drive was held between January and April though officers said it still continues. Officers ensured the deportation of illegal immigrants with the help of the FRRO (Foreigners Regional Registration Office).
In February, Union Home Minister Amit Shah had also directed police to take strict action against networks that help illegal Bangladeshis and Rohingyas enter India, including those who help them get fake documents. In 2025, around 22,00 Bangladeshis were deported from Delhi, compared to 14 in 2024 and 5 in 2023. The majority of the Bangladeshis entered through the West Bengal border, police said.
