The Central Bureau of Investigation has filed a new case against a current and a former employee of Punjab National Bank’s Brady House branch in South Mumbai, three weeks after they were arrested in connection with the alleged fraud involving jeweller Nirav Modi, PTI reported on Thursday.

Former Deputy General Manager Gokulnath Shetty and single window operator Manoj Kharat allegedly used the same modus operandi to issue fraudulent Letters of Undertaking to another company in 2017, the agency alleged in its case filed on March 9. The two are accused of criminal conspiracy, breach of trust, cheating and abuse of an official position, a copy of the First Information Report with The Indian Express showed.

The case is related to Letters of Undertaking worth over Rs 9 crore issued by the Brady House branch to Chandri Papers and Allied Products. The CBI also named the company and its directors in the case and has reportedly began searches at various locations.

The CBI alleged that Chandri Papers and Allied Products got two Letters of Undertaking issued by the branch in April for loans worth $1.4 million (Rs 9 crore) favouring State Bank of India’s Antwerp branch in Belgium. The payment for the LoUs is due on January 20, 2020.

Shetty and Kharat were among the first people to be arrested after the alleged Rs 11,380-crore fraud at PNB’s Brady House branch was reported. The amount of the fraud is now said to be over Rs 13,000 crore.

The Reserve Bank of India on Tuesday discontinued LoUs issued with regard to trade credits for imports with immediate effect.
