Dhaka Metropolitan Magistrate Dhiman Chandra Mondol passed the order on Monday after police sought eight days to question the alleged fraudsters.
The suspects are all Ukrainian nationals, said Ashraful Islam, a court officer.
They are Denys Vitomskyi, 20, Nazarii Vozniuk, 19, Volodymyr Trishchynskyi, 37, Serheii Ukrainets, 33, Oleg Shevchuk, 46, and Valentyn Sokolovskyi, 37.
A foreign national was arrested while withdrawing money from the Dutch Bangla Bank ATM booth located in front of Dhaka’s Khilgaon Taltala Market, according to a police report submitted to the court.
After interrogating him, police arrested five others at a city hotel at Panthapath.
Mashiur Rahman, Dutch-Bangla Bank Limited head of alternate delivery channel, started the case with Khilgaon police under the ICT Act on Sunday. The detective police have been put on the case.
Apart from Khilgaon Taltala Market, two foreign nationals withdrew money several times from the Dutch-Bangla Bank ATM booth at Dhaka’s Badda on Friday night, according to the case.
The money was not taken from any customer's account. No account of that transaction has been recorded in the bank’s main server. But the bank authorities found that Tk 300,000 was withdrawn from the booth.
The fraudsters used a new technology to withdraw the cash from the ATM booth. Police are trying to find out the technology they used.
