Officers probing the credit card fraud allegedly perpetrated by a delivery man of a courier firm and four others suspect that the accused had duped more people than they had initially thought.
Police had earlier said that Soumen Dorji, the delivery man, and the others had fraudulently used three credit cards.
The delivery man, the cops said, would take out a card from a sealed envelope before handing it over to the customer and swipe it at a shop.
Then, while delivering the card he would coax the customer into sharing his personal details. The racket would use the details to temporarily block transaction messages from going into the customer’s cell phone. Dorji and his associates would use this window to make online transactions.
All three cards the police said the gang had fraudulently used were issued by one bank. The gang had allegedly made transactions worth Rs 3.88 lakh using the three cards belonging to residents of North 24-Parganas.
“We have learnt that several other banks send credit cards to their customers through the same courier company. We are getting in touch with the banks to know whether they have come across suspicious online transactions using credit cards issued by them,” said an officer.
Dorji, the officer said, has admitted during interrogation that he had compiled personal details of several credit card-holders.
“Dorji has good communication skills. He would smartly ask the card-holders a few personal questions, as if the exercise was part of a security drill. Unsuspecting customers would share their personal details with him,” said an officer.
“As part of an aggressive marketing strategy, banks often hire agents or direct sales officers, who are not on the staff, to interact with their clients. Confidential data related to clients often get leaked at this level,” the officer said.
