The Rapid Action Battalion (RAB) detained eight persons from different parts of the capital on Saturday night for their alleged involvement in withdrawing around Tk 30 million from Dutch-Bangla Bank Limited's (DBBL) ATM booths through forgery.
The detainees are members of an organised crime syndicate and employees of Garda Shield Security Services Limited, said RAB media wing director Khandaker Al Moin at a briefing on Sunday afternoon.
The arrested persons are-Abdur Rahman Biswas, Tarek Aziz, Tahmid Uddin, Robiul Islam, Habibur Rahman, Kamrul Hasan, Sujon Mia, and Abdul Kader.
The RAB director said DBBL assigned Garda Shield Security Services to manage its ATM booths as a third party. The bank authority noticed some abnormalities in their balance sheets and ATM booth operations as well as received complaints from clients.
The bank found mismatch of around Tk 30 million from at least 200 ATM booths across the city.
The accused, while loading cash into ATM machines, intentionally created jam in cash flow of the machines by folding bank notes.
Subsequently, the clients failed to withdraw money after giving commands to do it, and the money fell into a bin inside the ATMs, which was later collected and embezzled by the arrested persons, Mr Moin added.
