Kolkata Airport bomb hoax: CISF finds nothing after full search
Synopsis
Kolkata Airport's second major bomb hoax episode of 2026 — a threatening email claiming explosives were hidden inside the terminal sent CISF into a full sweep on 8 October. Nothing was found, but the pattern of repeated hoax threats at the airport and across West Bengal's government offices is prompting a cyber forensics crackdown to identify those responsible.
Key Takeaways
Netaji Subhas Chandra Bose International Airport , Kolkata , received a bomb threat email on 8 October 2026 .
The email claimed explosive devices were hidden at multiple locations inside the airport premises.
CISF personnel conducted a thorough search; no suspicious objects were found.
Cyber experts have been engaged to trace the source of the threatening email.
In February last year , two similar hoax threats were reported at Kolkata Airport on the same day.
Earlier in 2026 , bomb threat emails also targeted post offices and passport offices across West Bengal , all of which proved to be hoaxes.
Netaji Subhas Chandra Bose International Airport in Kolkata was placed on high alert on Thursday, 8 October 2026, after authorities received a threatening email claiming that bombs had been placed at multiple locations inside the airport premises. The Central Industrial Security Force (CISF) launched an immediate and thorough search operation across the facility. As of the latest available information, no suspicious objects have been detected.
The Threat Email
According to sources aware of the development, the threatening email was received by airport authorities on Thursday afternoon. The message claimed that explosive devices had been stocked at certain spots within the airport. Officials promptly alerted CISF personnel — the force responsible for security at the airport — who swung into action without delay.
Although there was an initial assessment that the information could be false, authorities reportedly decided against taking any chances and ordered a comprehensive sweep of the premises. The alert caused brief panic inside the airport before the situation was brought under control.
Search Operation and Cyber Investigation
CISF jawans conducted a systematic search of the airport premises. According to available information, the operation has so far yielded no trace of any explosive material or suspicious object. In parallel, efforts are under way to identify the individual or individuals behind the threatening email. Cyber experts have reportedly been brought in to trace the source of the communication.
A Recurring Pattern at Kolkata Airport
This is not the first time Kolkata Airport has been targeted by a bomb hoax. In February last year, two such scares occurred on the same day — a threatening note written in lipstick was discovered in the toilet of one flight, while a similar written threat was found on a second aircraft. Both were subsequently confirmed to be hoaxes.
Separately, also in February this year, several post offices and adjoining passport offices across multiple districts of West Bengal received bomb threat emails during office hours, triggering evacuations. Extensive searches by police and bomb disposal squads in those cases, too, found nothing. This marks at least the third such episode linked to Kolkata's aviation and government infrastructure in recent months.
What Happens Next
Airport operations are expected to continue as security personnel remain on heightened alert. Investigators are focused on tracking down those responsible, with cyber forensics playing a central role. Repeated hoax threats carry serious legal consequences under Indian law, and authorities have signalled that they intend to pursue the matter to its conclusion.
Point of View
However implausible, will trigger a full security response and cause disruption, making the hoax itself the weapon. Authorities have repeatedly confirmed 'nothing found' without publicly announcing arrests or prosecutions, which may be inadvertently signalling low risk to would-be hoaxers. Until cyber forensics actually produces a named accused who faces swift legal consequences, the cycle is likely to continue. The West Bengal pattern — airports, post offices, passport offices all receiving similar emails — also suggests a coordinated actor or copycat culture that warrants a coordinated state response, not just case-by-case searches.
