Mamta Kumari, a former Deputy Branch Manager of ICICI Bank’s Chetla branch in Kolkata, was arrested on August 8, 2026, from Ballia, Uttar Pradesh for allegedly forging the signature of an elderly account holder to liquidate his fixed deposit and making unauthorised online transactions using a credit card he had formally surrendered in 2020, during the pandemic.
The deputy branch manager quit her job the following year and allegedly wiped her electronic trail.
Mamata Kumari was arrested in Ballia, Uttar Pradesh, on Saturday, after police managed to catch her ending a three-year chase.
Police said the woman managed to carry out the fraud for three years without detection because the elderly man did not realise that he was no longer receiving text alerts from the bank on his phone.
According to a complaint lodged by the bank’s branch manager, the elderly man had approached the bank during the pandemic to surrender his credit card.
The accused, Mamata Kumari, was the deputy branch manager at the time.
She accepted the application, took physical possession of the credit card and forged a document giving him the NOC required to surrender the card.
Unfortunately, the elderly man did not know that when a credit card is surrendered, the bank official has to break it into pieces in front of the customer to ensure it is not misused in the future.
The deputy branch manager then allegedly forged the elderly man’s signature on a KYC document and applied to change the phone number and email address linked to the credit card.
Once the credit card details were shifted to another number, there was no way the old man could have received an alert when the woman made the online transactions and exhausted the card limit of ₹1 lakh.
She then liquidated one of his FDs and transferred the money. All this while, the man neither received any alert about the transactions nor realised the fraud, as he had not made any online transactions during this period.
The Chetla branch lodged a complaint in 2023, following which a probe was initiated. And now after 3 years she was finally arrested.
