One of the 12 banks, where part of Rs 1 crore that was fraudulently transferred from the account of a director in a private firm, did not follow proper banking procedures while transferring the money, said the police.
Fraudsters had transferred Rs 9.7 lakh to the bank account.
"The bank did not follow a proper withdrawal procedure. The cashier did not intimate the manager while the fraudster was withdrawing such a hefty amount," said Quaisar Khalid, additional commissioner of police, eastern region. "A customer who intends to remove such a huge sum has to be intimate the bank, but that wasn't done."
The money was siphoned off from the director's company's account through real-time gross settlement (RTGS) last Thursday. It was transferred to 12 different accounts in banks across the country. Of those, five banks are in and around the city and the rest are across the country.
Officers are probing if any bank employee was involved. Investigations are also on if the banks followed mandatory procedures while opening these 12 accounts such as verification of documents. The police are finding details of the owners of these accounts. "We are investigating if banks had followed procedures such as talking to the 'introducer' before opening the account. An introducer is someone who has an account in the bank and introduces the prospective customer to the bank," added Khalid. "We have also sent teams outside Mumbai."
The police had arrested Troy Ral Pereira, 32, who had gone to a bank to withdraw Rs 10 lakh out of the Rs 30 lakh credited in his account last Friday. The kingpin, who transferred the money, is yet to be arrested.
