Maharashtra Chief Minister Devendra Fadnavis said on Friday that he had received a letter from a Maoist group threatening to kill him. “I have received this letter and I have forwarded it to the police. An investigation is under way,” said Mr. Fadnavis. He, however, refused to divulge the details of the letter. According to sources, two letters on May 13 and 18 targeting Mr. Fadnavis, his family and police officers who were part of an anti-naxal operation in Gadchiroli were sent to Mantralaya. One of the letters is from the central committee of the Communist Party of India (Maoist) and the other from Dandkaranya special zonal committee, sources said. The letters were handed over to senior police officials. “The case has been handed over to the State intelligence department for investigation and the CM’s security has been beefed up,” said a senior Mumbai Police officer. Mr. Fadnavis told media persons that the police during investigations had found internal communication pertaining to an assassination attempt on Prime Minister Narendra Modi along the lines of the Rajiv Gandhi killing. “We have got a lot of evidence from their internal documents. Naxalism is no longer limited to the jungles. It is also present in urban areas,” said Mr. Fadnavis. The Chief Minister said that there were naxal operatives in cities who were misleading the people.
