Nagpur, Apr 30: A high‑security alert has been sounded across Nagpur after an anonymous letter claimed that radioactive material had been planted at several key locations, including the RSS headquarters and a BJP office, officials said on Thursday.
The letter, written in English and purportedly sent by an organisation calling itself “DSS”, was received on April 27 at the office of Nagpur Police Commissioner Dr Ravinder Singal via post, police sources said. It contains highly objectionable remarks and warns that Caesium‑137, a highly radioactive substance, has been placed at multiple sites in the city.
The letter specifically mentions the Rashtriya Swayamsevak Sangh (RSS) headquarters (Mahal), the Smriti Mandir complex in Reshimbagh—a memorial dedicated to RSS founder Dr K B Hedgewar and former RSS chief M S Golwalkar—and a BJP office in Ganeshpeth. It also claims that the radioactive material has been concealed under the seats of Metro trains on the Orange and Aqua lines and “Aapli Bus” city buses operating near these locations. The sender further alleges that the substance was sourced from a cancer hospital and warns of a city‑wide radiation threat.
After receiving the letter, police immediately activated all emergency protocols and formed multiple teams, including the Anti‑Terrorism Squad (ATS), the National Disaster Response Force (NDRF), and atomic‑energy experts. Extensive searches have been carried out at all the locations named in the letter, with special equipment used to detect any radiation or hazardous material. So far, however, no traces of radioactive material have been detected.
Officials suspect that the letter could be a hoax aimed at creating panic, but the probe is being treated with utmost seriousness. A case has been registered at Sadar police station based on a complaint filed by the ATS, and efforts are underway to trace the origin of the letter and identify those behind the “DSS” group.
The letter also refers to the recent recovery of detonators and gelatin sticks near Dosar Bhavan Metro Station, claiming responsibility and calling it a “warning”. This has prompted additional scrutiny of recent suspicious finds and possible links to earlier incidents. Security has been significantly tightened, especially around the RSS headquarters, which is already under round‑the‑clock protection by CISF and Nagpur Police personnel.
“Surveillance has been increased, and we are not taking any chances,” a senior ATS official said. “We are monitoring all sensitive locations and public transport nodes while the investigation progresses on multiple fronts.” City authorities have also appealed to the public to remain calm, avoid spreading unverified rumours, and report any suspicious activity or objects to the police immediately
