The Wilson Garden police have arrested a man accused of sending a threatening e-mail to the Bengaluru Metro Rail Corporation Limited (BMRCL), warning that one of the city’s Metro stations would be blown up. The arrest was confirmed on Tuesday by Bengaluru Police Commissioner Seemant Kumar Singh, who also indicated that the suspect may be mentally unstable.

The threat e-mail, sent late on November 13, triggered immediate concern within BMRCL and led to the registration of a formal case. After preliminary assessment, police declared the threat a hoax, but a full investigation was initiated due to the sensitive nature of the message.

Threat e-mail triggers probe at BMRCL

According to the FIR, the threatening e-mail was received at 11:25 pm on November 13 on the official BMRCL address from [email protected]. The message warned BMRCL that if the sender believed the Metro staff were “torturing mentally” his former wife after duty hours, then one of the stations would be “blasted”.

The threatening text included a reference to being a “terrorists liker PATRIOTIC against KANNADIGAS”, further raising red flags for cyber investigators and Metro authorities.
Rathish Thomas, 50, Assistant Executive Engineer (Cybersecurity) at BMRCL, filed a complaint on November 14, based on which police registered a non-cognizable report (NCR).

However, after obtaining court permission, the Wilson Garden police registered a formal FIR on November 15, booking the case under Bharatiya Nyaya Sanhita (BNS) Section 351, which pertains to criminal intimidation.

Police arrest suspect; mental health concerns raised

Commissioner Seemant Kumar Singh said the suspect was arrested from within the city limits and taken into custody for questioning. While the police have not yet released the personal details of the accused, preliminary interactions with him suggested significant inconsistencies in his statements.

“The suspect appears to be mentally unsound. The person named in the e-mail was his wife. However, his statements don’t tally. He has been further referred to NIMHANS for evaluation,” Singh stated.

Police officials noted that the mention of the suspect’s former wife in the threatening mail hinted at possible domestic disputes or personal grievances rather than any credible terror intent.

Hoax confirmed but security protocol followed

Even though investigators soon concluded that the threat was not credible, authorities emphasised that procedural precautions were undertaken. Sensitive infrastructure such as Metro rail systems remain high-risk targets, and every threat—even one likely to be a hoax—must be thoroughly verified.

BMRCL officials confirmed that cybersecurity teams collaborated with the police to trace the origin of the e-mail, check for vulnerabilities, and ensure operational safety. No Metro station reported any unusual activity in the hours following the threat.

Officials said that the Metro services were not disrupted, and passengers were not informed immediately to prevent unnecessary panic.

Legal action and ongoing investigation

Under BNS Section 351, criminal intimidation involving threats to life or property is a punishable offence. The police are currently examining digital evidence from the suspect’s devices, including computers, phones, and e-mail accounts, to establish whether he acted alone and to verify his mental health claims.

Authorities are also interviewing the suspect’s former wife to understand whether she was under any perceived pressure, as mentioned in the e-mail. Investigators said that the e-mail contained irrational phrasing and contradictory elements, strengthening the suspicion of mental instability.

“Cases involving threats to public transport systems must be dealt with firmly, regardless of the sender’s mental condition. The investigation is ongoing,” a senior officer said.

Security concerns amid high public footfall

The Bengaluru Metro sees lakhs of commuters daily, and security threats of any nature are taken seriously. Metro infrastructure has been subject to past hoax threats, but authorities underline that each incident reinforces the need for robust cybersecurity systems.

The arrest comes at a time when the city is preparing for several high-footfall events, increasing vigilance among law enforcement agencies. BMRCL has stepped up internal monitoring and is conducting a review of its e-mail security systems following the incident.

Conclusion

The arrest in the BMRCL threat mail case highlights the growing challenge of digital hoaxes impacting public safety infrastructure. While the suspect appears to have acted out of personal grievances, the case underscores the seriousness with which law enforcement must respond to threats targeting mass transit networks. The investigation continues, with police awaiting a detailed mental health assessment report from NIMHANS before deciding the next steps.
