The maximum punishment for the offence under section 409 of the IPC (criminal breach of trust by public servant, or by banker, merchant or agent) is life imprisonment.
Among others, the agency has arrested Gokulnath Shetty, the then deputy manager (now retired) of PNB, in connection with issuance of fraudulent letters of undertaking (LoUs) to Choksi-owned firms.
"The acts of Shetty prima facie disclose commission of offence punishable under section 409 IPC along with other offences already alleged in the FIR," read the CBI's submission before the special court.
The CBI has alleged that firms controlled by diamond traders Nirav Modi and his uncle Mehul Choksi obtained fraudulent LoUs and letters of credit (LCs) worth USD 2 billion (Rs 12,636 crore) from PNB in connivance with bank officials.
