The CBI has received two complaints from the PNB against billionaire jewellery designer Nirav Modi and a jewellery company about fraudulent transactions worth Rs 10,000 crore, official sources said on Wednesday.
The report came as the Punjab National Bank (PNB), India's second-biggest state-run bank, said on Wednesday that it has detected a $1.8 billion fraud at a single branch in Mumbai, the impact of which could extend to other lenders as well.
The agency received the complaints about the transactions detected by the public sector bank late last night, sources said.
The complaints deal with fraudulent transactions reported from the bank's branches and the amount involved is over Rs 10,000 crore, the sources said.
The allegations are being looked into and future course of action will be decided soon, they said.
The agency has refused to share any further details as it may hamper the investigation.
Agency sources said Modi is already facing a CBI probe on a complaint from the Punjab National Bank.
