New Delhi, March 15: Apparently, the Nirav Modi and Mehul Choksi groups were not the only ones indulging in frauds related to Letters of Undertaking (LoUs) issued by the Punjab tiol Bank (PNB) officials. The Central Bureau of Investigation (CBI) has filed another case against former Deputy Mager of PNB, Gokulth Shetty — who was arrested in multi-crore fraud involving Modi and Choksi — for allegedly issuing Letters of Undertaking worth Rs 9.09 crore to Chandri Papers. Besides Shetty, PNB’s Brady House Branch in Mumbai’s Single Window Operator Manoj Hanumant Kharat and Directors of Chandri Papers — Aditya Rasiwasia and Ishwardas Agarwal — have also been med in the CBI FIR registered on March 9. The CBI registered the fresh case against Shetty following a complaint filed by the PNB on the same day.
