Authorities suspect a repeat offender behind recent bomb threats to the Delhi and Bombay High Courts, with Outlook emails mentioning ‘RDX’. Investigations are underway to identify the sender and prevent future incidents.

Repeat Offender Suspected in RDX Bomb Threats to Delhi and Bombay High Courts
Introduction
On Friday, September 12, 2025, both the Delhi and Bombay High Courts received bomb threat emails, leading to immediate evacuations and heightened security measures. Authorities suspect the involvement of a repeat offender responsible for similar hoaxes in the past.
Details of the Threats
Delhi High Court
The Delhi High Court received an email claiming that three improvised explosive devices (IEDs) had been planted within the premises. The message warned of explosions scheduled after the midday Friday prayers and specifically mentioned a judge’s chamber as the target. In response, the court was evacuated, and bomb detection squads were deployed to search the area.
Bombay High Court
Shortly after the Delhi incident, the Bombay High Court received a similar bomb threat email. The court complex was evacuated, ongoing hearings were suspended, and police along with bomb detection squads conducted thorough searches of the premises. Authorities acted swiftly to ensure the safety of all present in the building.
Suspected Repeat Offender
Investigations have revealed that the threat emails were sent using Outlook accounts and contained references to ‘RDX’. Mumbai police suspect that the same individual responsible for over a dozen similar hoax threats in the city over the past few months might be behind these recent incidents. These previous threats, which also turned out to be hoaxes, targeted various locations, including schools and public institutions.
Law Enforcement Response
Law enforcement agencies have intensified their efforts to trace the origin of the threat emails. Preliminary investigations suggest the use of virtual private networks (VPNs) and international email services to obscure the sender’s identity. Authorities are collaborating with cybercrime experts and utilizing advanced tracking technologies to identify and apprehend the individual responsible.
Impact on Judicial Operations
The bomb threats have disrupted judicial operations in both Delhi and Mumbai. In Delhi, the evacuation led to the suspension of court proceedings, causing delays in legal processes. Similarly, in Mumbai, the evacuation of the Bombay High Court complex halted ongoing hearings, affecting the timely delivery of justice.
Public and Institutional Reactions
The incidents have raised concerns about the security of judicial institutions in India. Legal professionals, including judges and lawyers, have expressed the need for enhanced security protocols to prevent such disruptions in the future. There is also a call for stricter measures to trace and penalize individuals who send hoax bomb threats, as they undermine public trust in the judicial system.
The recent bomb threat emails to the Delhi and Bombay High Courts highlight the ongoing issue of hoax threats targeting public institutions. While these threats have been deemed hoaxes, they have caused significant disruptions and raised serious security concerns. Authorities are committed to identifying and prosecuting those responsible to ensure the safety and integrity of judicial operations in India.
