As per CBI sources, arrested bank officials, during interrogation, disclosed that for every LoU, a commission was fixed depending on the amount to be sanctioned as loan. Commission in exchange of issuing the aforementioned document was distributed between all employees of PNB involved in it, the CBI said.



The investigation agency has also arrested Hemant Bhat, Authorised Signatory of the Nirav Modi Group of Firms.

Earlier in the day, it was reported that the Enforcement Directorate (ED) began raid at a Gitanjali store in Raipur in connection with the fraud case involving businessmen Nirav Modi and his uncle and business partner Mehul Choksi.

The agency had conducted searches at several places linked to Nirav Modi in Mumbai, Delhi, and Gujarat, and seized diamonds, jewellery and gold worth Rs 5,649 crore.

State-owned PNB has been rocked by a USD 1.77 billion scam where billionaire jeweller Nirav Modi allegedly acquired fraudulent letters of undertakings (LoUs) from the Brady House branch in south Mumbai to secure overseas credit from other lenders. The scam was started in 2011 and was detected in the third week of January this year, after which the PNB officials filed a complaint with the CBI on January 31.

The other banks which have or have had exposure to the fraud include State Bank of India (over USD 221 million), Allahabad Bank and Axis Bank among others. Some overseas lenders are also believed to have had exposure to the fraud.
