Mehta used forged BRs to gain unsecured loans, and used several small banks to issue BRs on demand. Once these fake BRs were issued, they were passed on to other banks and the banks in turn gave money to Mehta, assuming that they were lending against government securities when this was not really the case. This money was used to drive up the prices of stocks in the stock market. When time came to return the money, the shares were sold for a profit and the BR was retired. The money due to the bank was returned.
