I was cheated of 5 lakhs by a man in Kolkata how to file cheating case

Cheating involving a significant sum in Kolkata is punishable under Section 318 of the Bharatiya Nyaya Sanhita, which corresponds to the former Section 420 IPC. You should file an FIR at the police station having jurisdiction over the place where the fraud occurred, attaching all bank transaction records, messages, and agreements. The Economic Offences Wing in West Bengal may also take up cases involving larger amounts. If police do not register the FIR, you can file a private complaint before the Magistrate under Section 223 BNSS. For substantial financial fraud, approaching the Calcutta High Court under West Bengal Premises Tenancy Act 1997 for a monitored investigation may also be considered.
