MUMBAI, June 8 -- The police on Thursday booked a 34-year-old man for allegedly sending threatening, abusive, and defamatory messages, and trying to extort money out of an assistant municipal commissioner (AMC) at Mira Bhayandar Municipal Corporation (MBMC). The accused, Chandan Thakur, has been booked earlier for defaming over 15 government officials and demanding money from them. The complainant, Yogesh Gunijan, works in ward 1 of the municipal corporation where his role is to check for illegal constructions, act against them, recover property and other taxes and give birth and death certificates, said the Bhayandar police. Gunijan told the police that on April 23 he received messages from Thakur claiming that more than 10 bungalows were being illegally constructed in his jurisdiction with no action being taken against them. Thakur sent the details to Gunijan's official email too. According to the police, Thakur would file complaints about illegal buildings in his locality, and when the MBMC would urge the two parties to come to a settlement, he would extort money from people. On June 4, Thakur called Gunijan to say that since the latter was not taking action on his complaints, he was not allowing him to make money from settlements with people who had built illegal constructions in the Uttan area. The police said that on May 14, an anonymous social media handle posted messages in an abusive language accusing the assistant commissioner of corruption and making several other allegations. The police added that the language of the posts was similar to Thakur's from messages in previous cases. The police said that Thakur demanded Rs.50,000 from the AMC, threatening to defame him and his family on various social media accounts if he did not comply. Thakur had earlier defamed the AMC and his wife, in an already registered complaint, and the police have now booked him under sections 308 (extortion), 351 (criminal intimidation) and 356 (defamation) of the Bharatiya Nyaya Sanhita (BNS)....
