BharatPe's ex-MD Ashneer Grover has written a letter to RBI, asking for a probe into the company's shareholding, ET reported. BharatPe "defrauded" RBI by bringing back Co-founder Bhavik Koladiya, who was convicted of wire fraud in US, to the company's cap table, the letter said. Grover asked RBI to revoke all licences of BharatPe if the company is found guilty.
