Axis's retail banking head Rajiv Anand said so far the investigating agencies had visited eight branches, including five in New Delhi, and the number of employees suspended has gone up to 24 from 19 last week.
"It is not that Axis Bank is under the scanner, but the person doing the transaction with us is," he said, adding at no point it has been asked to shut any branch.
The suspension of account is temporary and the bank carries out extra due diligence including a visit to account holder's address in some cases, he said.
