A high-security alert has been sounded across Nagpur after an anonymous letter claimed that radioactive material had been planted at key locations, including the RSS headquarters and a BJP office, officials said on Thursday.
Police said the letter was received at the office of Police Commissioner Dr Ravinder Singal on April
27.
The police have formed multiple teams and roped in the National Disaster Response Force (NDRF) and energy experts. They carried out extensive searches at the places mentioned in the letter, but have not found any traces of radioactive material so far. The police suspect that the letter could be a hoax, and a probe was underway.
