Ahmedabad,UPDATED: Mar 5, 2026 12:46 IST

A major breakthrough has been achieved in the nationwide hoax bomb threat case after investigators arrested the man accused of sending a series of threatening emails that triggered panic across multiple Indian cities.

The Gujarat Crime Branch, in a joint operation with the Ahmedabad Cyber Crime Unit, arrested 28-year-old Sourav Biswas from West Bengal for allegedly sending bomb threat emails targeting schools, courts, metro stations and financial institutions across the country.

Officials said the arrest marks the first major breakthrough in the investigation into a wave of threatening emails that caused widespread alarm among security agencies and the public.

According to investigators, the accused allegedly sent more than 50 bomb threat emails over the past five days to locations in Mumbai, Delhi, Gujarat and several other states. Among the targets were schools, metro stations and even the stock exchange in Mumbai.

The man also triggered panic in Mumbai on February 27 when, at around 8:46 am, threatening emails were sent via the internet to several schools and metro stations in Mumbai, warning of bomb blasts within two days. The message immediately set off alarm bells among security agencies, prompting emergency checks and evacuations at multiple locations.

Following the threat, a case was registered at the Dindoshi Police Station in Mumbai and a technical investigation was launched. Cyber experts began tracking the digital trail of the email, eventually identifying the source in the New Barrackpore area of West Bengal.

Police teams were dispatched to the state to locate the suspect.

During the investigation, authorities also discovered that the same accused had earlier sent a similar threatening email in Ahmedabad on February 16. The Ahmedabad Cyber Crime Police had already registered a case in connection with that email.

Acting on intelligence inputs and digital tracking, Ahmedabad Crime Branch officials detained the suspect on March 1. Mumbai Police later took custody of the accused as part of the ongoing investigation.

Officials confirmed that the accused has now been brought into custody and placed on remand. Investigators are currently interrogating him to determine the motive behind the threats, the technology used to send the emails and whether any accomplices or larger network may be involved.

Police said preliminary questioning suggests the threats may have been sent with the intention of creating panic, but investigators are not ruling out other possibilities.
