Hit by a Rs 11,400 crore fraud, state-owned Punjab National Bank (PNB) has cautioned other banks about the modus operandi of the scam.
"It has been reported through a preliminary investigation that the suspected fraud has been carried out by the perpetrators in collusion with the staff of one of the our branches in Mumbai," PNB said in a letter sent to various banks, including those from the private and public sector as also to foreign lenders.
The letter said it was found through the SWIFT trail that one junior level official unauthorisedly and fraudulently issued Letters of Undertaking (LoUs) on behalf of some companies belonging to Nirav Modi Group.
The companies were maintaining only current accounts with the branch and none of the transactions were routed though the Centralised Banking System, it said.
PNB said that RBI norms were overlooked by overseas branches of other Indian banks and alleged connivance of group companies of Nirav Modi and Gitanjali Gems with its own official and also apparently of others working in foreign branches of Indian banks.
The fraudulent act was found out when subsequent to superannuation of the concerned official, the same companies again approached the branch for availing Letter of Undertakings (LoUs).
