NAVI MUMBAI, Dec. 6 -- A 71-year-old Vashi resident lost Rs.1.6 crore after falling prey to an online investment racket operating through WhatsApp groups and fake trading applications. According to the complaint, the senior citizen, who runs a transport business, was added without his knowledge to a WhatsApp group on November 1. The group had members engaged in stock trading, claiming large profits. "A woman in the group acted as an investment guide, posting updates on stock trades and IPOs. Her messages, along with the apparent profits of others, convinced the victim that the platform was genuine," a police officer said. On November 4, the man received a link to a trading app. "The app showed real-time charts and profits, mimicking authentic trading platforms," the police officer added. Between November 6 and November 27, the victim made 12 bank transfers totalling over Rs.1,6 crore into multiple accounts, with the largest single transfer being Rs.40 lakh. On November 28, when he attempted to withdraw the money, the scammers began to make excuses and pressuring him for more money. The victim soon realised he had been cheated, and filed a complaint on the National Cyber Crime Reporting Portal (NCCRP)....
