Nagpur, India — April 30, 2026
Nagpur has been placed under heightened security after authorities received an anonymous threat letter alleging that radioactive material had been dispersed across multiple high-profile locations, including the Rashtriya Swayamsevak Sangh (RSS) headquarters.
According to police officials, the letter—delivered to the office of Police Commissioner Dr. Ravinder Kumar Singhal on April 27—claimed that a dangerous radioactive substance had been planted at key sites in the city. These locations reportedly include the RSS headquarters in Mahal, the Dr. Hedgewar Smriti Mandir in Reshimbagh, a BJP office in Ganeshpeth, metro train coaches, and public transport routes near political offices.
The letter, allegedly sent by a group identifying itself as “DSS,” used inflammatory language and issued a warning suggesting that the entire city could be at risk of radiation exposure.
Investigation Intensifies Across Multiple Agencies
Following the threat, the Maharashtra Anti-Terrorism Squad (ATS) launched an immediate investigation, coordinating with the National Disaster Response Force (NDRF) and nuclear experts.
Search operations were carried out at all locations mentioned in the letter, including metro stations, RSS facilities, and surrounding public areas. However, preliminary findings from radiation detection teams have not identified any trace of radioactive contamination so far.
Authorities say the absence of evidence suggests the threat may be a hoax, but officials are continuing to treat the situation with utmost seriousness.
What the Letter Claimed
The anonymous communication alleged the use of Cesium-137, a highly radioactive isotope known for its potential health risks. The letter claimed that the substance had been sourced from a cancer treatment facility and dispersed at various sites.
Cesium-137 is not naturally occurring and is typically produced as a byproduct of nuclear fission in reactors or weapons. It emits beta particles and strong gamma radiation, with a half-life of approximately 30 years, making it particularly hazardous if released into populated environments.
The letter further referenced a recent incident in which explosive materials and gelatin sticks were found in an open field near a metro station. The group claimed responsibility for that discovery, calling it a “warning” and hinting at further escalation.
Security Tightened Across Nagpur
Police have significantly increased security across the city, particularly around sensitive installations. The RSS headquarters is currently under a multi-layered security cover involving over 150 personnel from the Central Industrial Security Force (CISF) and local police.
Surveillance has also been intensified at metro stations, government offices, and public transport systems. Authorities are tracking the origin of the letter and attempting to identify individuals or groups behind the threat.
A case has been registered at Sadar Police Station based on a complaint filed by the ATS. Officials confirmed that forensic and cyber teams are analyzing the letter and postal trail for leads.
Officials Urge Calm Amid Ongoing Probe
While early assessments indicate no immediate radioactive risk, officials have urged the public to remain vigilant but not panic. Experts from nuclear agencies, including those linked to the Tarapur Atomic Power Station, may be consulted if further verification is required.
Authorities emphasized that spreading misinformation or panic would be taken seriously, as the investigation continues to determine whether the threat was a deliberate attempt to create fear or part of a larger conspiracy.
