New Delhi, April 3 - State-run lender Punjab National Bank (PNB) has said its customers' "money is safe with us".

We are and will always be committed to our customers." On the recent fraud, PNB said that it has a "zero tolerance to unethical practices within the system". "That is why the minute the bank became aware about discrepancies related to the recent incident, the fraudulent transactions were immediately reported to the regulator and the law enforcement agencies."
