Please provide a short summary on Harshad Mehta scam.

Context: Harshad Shantilal Mehta was an Indian stockbroker and a convicted fraudster. Mehta's involvement in the 1992 Indian securities scam made him infamous as a market manipulator.

Of the 27 criminal charges brought against Mehta, he was only convicted of four, before his death at age 47 in 2001. It was alleged that Mehta engaged in a massive stock manipulation scheme financed by worthless bank receipts, which his firm brokered for "ready forward" transactions between banks. Mehta was convicted by the Bombay High Court and the Supreme Court of India for his part in a financial scandal valued at ₹100 billion which took place on the Bombay Stock Exchange.
