MUMBAI, Sept. 6 -- The traffic police helpline and the police control room received threatening calls and messages claiming that 34 cars carrying human bombs will be used to detonate 400kg of RDX, explosive material, on Anant Chaturdashi. The alleged threats claim to target 10 million people on a day when massive crowds gather on streets and beaches to bid farewell to ganapati idols which are immersed either in the sea or in artificial ponds. The threatening calls and messages claimed to originate from an organisation called Lashkar-e-Jihadi, and added that 14 Pakistani terrorists have entered the city. Police officers responded that city residents need not panic since robust security arrangements have been put in place. A police officer said, "We are co-ordinating the bandobast (arrangement) for Anant Chaturdashi with the Brihanmumbai Municipal Corporation (BMC)." According to the police, there are around 6,500 Ganesh mandals in the city, and their idols are to be immersed on Saturday, the tenth day of the Ganapati festival. In addition, over 200,000 families have idols at home, which will be immersed in the 65 natural water bodies and 205 artificial ponds created by the BMC specifically for idol immersion. "We have cleared all the roads on the immersion routes, CCTV cameras have been installed at various routes and the visarjan spots like Girgaon, Dadar and Juhu Chowpatties, which attract the largest crowds on Anant Chaturdashi," said a police officer. Twelve additional commissioners of police, 49 deputy commissioners, 61 assistant commissioners, around 3,000 inspector-cadre officers and nearly 18,000 members of the police constabulary have been deployed for the occasion, the police added. According to the officer, besides the regular police force, the State Reserve Police Force (SRPF), Central Reserve Police Force (CRPF), Riot Control Force and Bombay Detection and Disposal Squad (BDDS) have also been posted at various immersion points....
