A 56-year-old man in Bengaluru lost Rs 6.54 crore in an online stock trading scam after he was led into a trap by scamsters promising a 1,500 per cent return on his investments through a phony app. Ramesh Kumar, director of a private firm, used to trade stocks through his demat account and watch YouTube channels for stock advice and updates. In a similar online crime last year, a retiree, another Bengaluru resident, lost Rs 9.14 crore to fraudsters.
