A 35-year-old man was arrested from his house in Asansol for allegedly duping an elderly man by posing as a bank official, police said.

Rajesh Kumar Mondal, 25, had allegedly called up Baguiati resident Rama Prasad Chakraborty, 72, and introduced himself as assistant manager of the bank where Chakraborty has a savings account. After getting the account details, he transferred the money to another account.

“We found that the stolen money was sent to a single account. A debit card attached to the account was used to buy electronic items from a shop in Asansol. We tracked down Kumar through the store,” the officer said.

The police are trying to find out whether Kumar had duped anyone else.
