Mumbai, April 11 -- A 63-year-old retired railway employee from Mulund has been duped of Rs.1.49 crore by cyber fraudsters who allegedly lured her with promises of high returns through an online share trading scheme. According to police, the woman came across an online advertisement on December 26 promoting lucrative stock market investments. After clicking on it, she was added to a WhatsApp group titled "VIP Share Trading Platform" with around 90 members. The group administrators regularly shared investment tips, while several members posted claims of earning substantial profits, prompting the woman to invest. Gaining her trust, the fraudsters persuaded her to invest larger sums, with the app displaying huge returns. By March 2, she had transferred Rs.1.05 crore across 31 transactions to bank accounts provided by the accused, the officer said. "When the app reflected a balance of Rs.7 crore, she attempted to withdraw funds but could not. The fraudsters then demanded Rs.88 lakh as charges and taxes, later offering a "discount" and asking her to pay Rs.44 lakh. She complied but still could not access her funds," he added. In a further attempt to extract money, the accused sent forged letters purportedly from the Securities and Exchange Board of India (SEBI), providing receipts for her investment of Rs.1.49 crore, asking her to invest more. Realising the fraud, she approached the police, who registered the case on Wednesday....
