Ketan Parekh, a notorious stock market manipulator, used mobile phones, including one linked to his wife, to conduct a front-running operation involving non-public information (NPI). Sebi’s investigation exposed a Rs 65 crore scam, revealing a complex network of agents, traders, and facilitators. The investigation, using mobile tracking and data analysis, linked Parekh to fraudulent trading activities orchestrated with a Singapore-based trader, Rohit Salgaocar. Sebi has now barred Parekh and Salgaocar from the Indian capital markets.
