"One accused has been arrested and we are looking for some more people in the case. The accused has withdrawn some cash from one of the accounts where Rs one crore was transferred," Additional Commissioner of Police (East Region) Quaiser Khalid told PTI.
However, the officer did not reveal the name of the accused as the entire amount was yet to be recovered and investigation is at a crucial stage.
On Thursday, complainant Ankur Korane received a number of messages stating that cash was being transferred from his bank account to other accounts electronically. In 45 minutes and after 12 transactions, nearly Rs one crore was stolen from him, police said.
Korane, a director in a cosmetic company, filed a complaint with Mulund police about the illegal transactions.
An FIR was registered on charges of cheating and impersonation under IPC and other relevant sections of the Information Technology Act.
The money was transferred from the bank's Mulund branch, using Real Time Gross Settlement system to different accounts, they said.
