MUMBAI, June 27 -- A 46-year-old official from the Income Tax department was duped of Rs.91.67 lakh in an investment scam by some cyber frauds. On Monday, a case was registered against the unidentified individuals for cheating and forgery. The Cyber police are investigating the case. According to the police, the victim came across videos of Rachana Ranade, a chartered accountant and an investment expert, on social media and expressed her interest in investing through the link mentioned in the post. She had also shared her contact details, after which she was added to a WhatsApp group where investment tips were shared, a police officer from the cyber cell said. She told the police that many people on the WhatsApp group were making immense profits, which encouraged her to invest similarly. She reached out to the group admin to get more details on how she could invest in order to make profits, as seen on the group. "They sent her a link through which she could install a mobile application. The app's name was similar to a multinational bank's name. She initially invested a small amount and made a 15% profit. They sent her forged acknowledgement letters from the multinational bank and Securities Exchange Board of India (sebi)," said the officer. From May 15 to June 3, she invested an amount of Rs.57.67 lakh by transferring the amount to various accounts as directed by the frauds, and the app reflected Rs.4 crore profit. On June 3, when she tried to withdraw the profits, she was asked to pay an amount of Rs.34 lakh as a service charge. "She paid the amount and then tried to withdraw the money. She was again asked to pay a security deposit of Rs.40 lakh. She then realised she had been cheated," said the police officer....
