I am a victim of online sextortion from someone in Kolkata; what should I do?

Online sextortion is prosecuted under Sections 75 and 351 of the Bharatiya Nyaya Sanhita for sexual harassment and criminal intimidation, read with Section 67 of the IT Act for obscene transmission. File an FIR at the Kolkata women's police station immediately and do not pay any money, since payment only deepens the extortion. The Calcutta High Court can direct the platform to remove the content and the police to trace the accused through the digital trail. West Bengal Premises Tenancy Act 1997 on women's safety may provide additional protections such as a state helpline and a dedicated women's cell in Kolkata. Preserve every message, the call logs and the recording of the video call without deleting the conversation. Inform a trusted family member in Kolkata to break the isolation that the extortionist exploits. The victim is not the accused, and the law protects the complainant from disclosure of identity under Section 372(3) of the BNSS.
