New Delhi:The Enforcement Directorate (ED) has summoned actor Prakash Raj for questioning in connection with a money laundering case linked to an alleged Rs 100 crore ponzi and fraud scheme by a Tiruchirapalli-based jewellery group. The federal agency conducted raids against Pranav Jewellers, seizing “unexplained” cash of Rs 23.70 lakh and some gold jewellery. Prakash Raj, aged 58 and a brand ambassador of the company, has been asked to depose before the ED in Chennai next week. The ED case originates from an FIR of the Tamil Nadu Police Economic Offences Wing, involving the collection of Rs 100 crore from the public under the guise of a gold investment scheme with the promise of high returns.
