West Bengal’s Special Task Force says it has broken up a suspected espionage network with roots in a Kolkata neighbourhood most residents would recognise from its shoe workshops rather than spy fiction. On the night of August 12, STF officers arrested a man from Bangaon in North 24 Parganas, close to the India-Bangladesh border, whom they identify as Rana Rauf alias Wahab Alam, a resident of Faisalabad, Pakistan. A second arrest followed from Topsia in East Kolkata: a local man investigators say helped Rauf build a fake Indian identity and settle into the city.
What investigators say happened
According to STF officials, Rauf entered India illegally through Nepal in 2012, stayed there for a period, and eventually moved into West Bengal. Over the years, he is alleged to have obtained fraudulent identity documents, including an Aadhaar card and voter card, with help from his Topsia contact, described in some reports as a local shoemaker.
Officers say Rauf had been tracking the movement of trains and armed forces personnel across the country, and investigators are now working to establish who, if anyone, that information was being passed to outside India. The STF has said it suspects contact with Pakistan’s Inter-Services Intelligence and, according to some reports, a network linked to a Pakistan-based operative. The man arrested in Topsia is being questioned to determine the full extent of his role and whether others in the city were involved.
Why the Kolkata connection matters
Topsia sits a short drive from the eastern fringe of central Kolkata, wedged between the EM Bypass and the railway lines threading out of the city, a dense, working neighbourhood rather than the kind of location typically associated with intelligence operations. That is, security officials note, precisely the profile such networks tend to look for: unremarkable localities where a new resident with the right paperwork draws little attention.
The case also lands in a charged calendar window. It surfaced just two days before Independence Day, a period when security agencies across Kolkata and the rest of Bengal routinely step up vigilance, tighten checks around railway stations and public gatherings, and review watchlists. Kolkata Dekho has previously reported on the layers of precaution Kolkata Police maintains around high-profile events and prohibitory orders during sensitive stretches of the calendar; this arrest fits into that same broader security posture, even though it was West Bengal’s STF, not the city police, that led the operation.
What happens next
Both men remain in custody as the STF works through Rauf’s contacts, movements, and communications since he settled in West Bengal. Investigators have not yet disclosed the identity of the Topsia resident, and no formal charges have been detailed publicly beyond the STF’s stated grounds for arrest. As with most cases at this early stage, the picture investigators eventually present in court, and the one circulating now, are not always the same, and Kolkata Dekho will update this story as the STF’s investigation develops.
Frequently Asked Questions
Who was arrested by the West Bengal STF?
STF officers arrested a man identified as Rana Rauf alias Wahab Alam, said to be a Pakistani national from Faisalabad, in Bangaon, North 24 Parganas. A second man was arrested from Topsia in East Kolkata on suspicion of helping him obtain fake identity documents.
What is he accused of?
Investigators suspect he was in contact with Pakistan’s ISI and had been tracking troop and train movements in India. The investigation into what information, if any, was shared outside the country is ongoing.
How did he enter India?
According to the STF, he entered India illegally through Nepal in 2012 before eventually settling in West Bengal.
Is the Topsia resident facing charges?
He has not been formally named in public statements. He is being questioned about the extent of his involvement and whether others assisted the network.
The bottom line
This is an active investigation, and several details, including the identity of the Topsia man and the full scope of what information may have changed hands, are still being established by the STF. Kolkata Dekho is treating the police account as the current state of the probe, not a final word, and will follow up as more is confirmed.
