Police complaint against wife for mental harassment and giving life threats

Yes. You can file an online complaint/e'FIR for physical assault, criminal intimidation, wrongful confinement or related offences and seek police protection; the BNSS expressly permits electronic reporting of cognizable offences (see BNSS s.173 on e'FIR/recording of information). Relevant substantive offences are in the BNS (e.g. hurt/assault, wrongful confinement, criminal intimidation -BNS ss.114,130,127,351). If a station refuses to record a cognizable offence you can escalate to the Superintendent or approach the Magistrate; the Supreme Court's Lalita Kumari principle requires registration of FIRs where a cognizable offence is disclosed and BNSS preserves escalation routes (see Lalita Kumari v. Govt. of U.P. and BNSS s.173(4)). Preserve all messages/calls/CCTV and report online also at the National Cyber Crime Portal.
