How was ₹597-crore fraud carried out at IDFC First Bank using a realtor & a jeweller?

The ₹597-crore Haryana government funds parked in IDFC First Bank's Chandigarh branch were siphoned off with realtor Vikram Wadhwa and jeweller Rajan Katodia's help. IDFC ex-employees Ribhav Rishi and Abhay Kumar transferred the funds to shell entities before transferring some of them to Katodia, who then falsely recorded gold items' sales. Rishi also used Wadhwa's companies to siphon the funds.
