evidence: Rajan who was speaking for the first time since the scam was exposed on 14 February said the fraud was something completely off the book. While responding to a query on reports claiming he had warned Rahul Gandhi and former finance minister P Chidambaram about Nirav Modi and the financial irregularities at PNB, Rajan said, "You leave India but India never leaves you. Social media has a habit of attributing complete rubbish to me." [...] The comments from the former RBI governor about the Rs 13,600 crore Punjab National Bank come on a day when the central bank issued a press statement banning the practice of issuing letters of understanding or letters of credit. The PNB scam which was allegedly masterminded by billionaire diamantaire Nirav Modi, his maternal uncle Mehul Choksi of Gitajali Gems centres around these LoUs and LoCs. The accused duo had hired PNB employees at Brady House branch in South Mumbai to get unauthorised and unmonitored LoUs to commit the fraud.
