Harshad Mehta was a stockbroker known as the "Big Bull" of Indian stock markets. In the early 1990s, he orchestrated a massive stock market scam by illegally diverting bank funds of Rs. 40 billion into the stock market. This triggered a huge rise and artificial inflation of stock prices. When the scam was uncovered, the Sensex fell dramatically, losing Rs. 100,000 crore in market value. The government took remedial measures like setting up a special court and committees to investigate, and Harshad Mehta was arrested and charged with multiple criminal offenses related to the scam.
