The complainant, a manager at a private company, informed police that he came across an investment link on Facebook and WhatsApp on July 25.
He initially invested ₹1 lakh and received a return of ₹4 lakh. Encouraged by the apparent success and further promises of high returns, he went on to transfer ₹1.4 crore into various accounts, even borrowing money from friends and relatives to invest.
The fraudsters created a fake online account displaying massive profits but stopped responding when he attempted to withdraw his money, an official said, citing the complaint.
Realising he had been duped, the man lodged a complaint at the Nagpur Cyber Police Station.
A case has been registered under the Bharatiya Nyaya Sanhita (BNS) and the Information Technology Act, and an investigation is underway, the official added.
