A gang of fraudsters has swindled many debit or credit card holders out of about Tk 10 million in the last five to six years.
The Criminal Investigation Department (CID) of police arrested the ringleader of the racket from Siddhirganj in Narayanganj on Sunday.
Mukta Dhar, special superintendent (LIC) of the CID, briefed reporters in this regard at the CID headquarters on Monday.
Mukta said Khokon had two Facebook IDs.
Through the Facebook accounts, he sent friend requests to different people and later made good relationships with them. At one point in their relationship, he wanted to know if they had bKash, Nagad, or Rocket accounts along with debit or credit cards.
If the targets had those, the members of the racket, introducing themselves as the officers of the mobile banking services, contacted them and asked to update their accounts. The criminals put wrong passwords on the mobile banking account numbers of the targets. The accounts were suspended automatically for three consecutive false passwords.
Then, the cheats informed them that their accounts were suspended temporarily and the balances in the accounts blocked.
After that, the cheats wanted to know the card number and card verification number (CVN).
When the targets sent their numbers to the fraudsters, the criminals asked for OTP codes.
When the targeted people provided them with OTP codes, the criminals transferred money from the victims’ debit and credit cards to their accounts.
Following a case filed by a victim with Demra Police Station on July 28, police investigated the incident and arrested the fraudster.
