A whistleblower complaint alleging insider trading, governance failures and shortcomings in forensic and audit reviews sent shares of IndusInd Bank Ltd 3 per cent lower in Wednesday's trade. Delivered to the Prime Minister's Office, the Reserve Bank of India (RBI) and multiple regulators seeking an investigation at IndusInd Bank, the complaint, as reported by ET, intensified scrutiny of the lender that earlier reported a Rs 2,000-crore derivatives accounting discrepancy.
