Mumbai, November 12: Security has been tightened across Mumbai after a threatening email warning of bomb blasts at several prominent locations, including the Mayor’s office, banks, a court, actor Amitabh Bachchan’s residence, Mahalaxmi Racecourse and Chhatrapati Shivaji Maharaj International Airport, triggered an alert among security agencies on Thursday.

According to sources, the threatening email was received on November 12 at 10:52 am from an email address identified as [email protected]. It was reportedly sent to several recipients, including officials of Punjab National Bank (PNB) in Mumbai, covering its Zonal Office, Local Credit Branch and branches at Cuffe Parade and Zaveri Bazar.

The email, purportedly signed by the “KHALISTAN National Army” and bearing the names of Eng. Guranakh Singh, Rukan Shahwala and Dr. Gurnirvair Singh Khan Rajada, contained threats of multiple explosions and attacks at different locations across the city.

Among the specific threats mentioned in the message was a bomb blast at a Punjab National Bank branch at 1:11 pm. It also warned of a possible explosion at Chhatrapati Shivaji Maharaj International Airport at 9:11 pm and referred to a purported bomb attack at Mahalaxmi Stadium.

Actor Amitabh Bachchan’s Juhu residence, Jalsa, was also mentioned in the email, with a warning of a possible car bomb attack. Singer Diljit Dosanjh was similarly named, with the message cautioning people against attending his upcoming shows.

The email further mentioned a court as a potential target at 2:11 pm and the Mayor’s office at 3:11 pm. The Brihanmumbai Municipal Corporation (BMC) was also reportedly named in the message, prompting authorities to strengthen security arrangements at its premises.

Following the receipt of the email, security agencies and law enforcement personnel were alerted. Security checks and inspections were subsequently conducted at the locations mentioned in the threat. However, no suspicious activity was detected during the searches, sources said.

Authorities are investigating the origin of the email and examining the credibility of the threats. Further details are awaited.

The latest threat comes weeks after Mumbai Police reportedly received another bomb threat targeting Amitabh Bachchan’s Juhu residence. The email, allegedly received by a school in the Bandra-Kurla Complex (BKC) area in October, had prompted police to launch an investigation.

On November 1, Bachchan greeted his fans during his customary Sunday interaction outside Jalsa. The veteran actor was seen standing inside a transparent protective enclosure, reportedly installed as an additional security measure. His son, actor Abhishek Bachchan, was also present during the interaction, while security personnel remained deployed at the spot.

Bachchan regularly steps out of his Juhu residence on Sundays to acknowledge and greet fans who gather outside his bungalow for a glimpse of the megastar.
