Under Section 176(3) of the BNSS, 2023, for offences punishable with imprisonment of seven years or more, which of the following is a mandatory obligation of the officer-in-charge of the police station?

Explanation: Section 176(3) of the BNSS mandates: "the officer in charge of a police station shall...cause the forensics expert to visit the crimes scene to collect forensic evidence in the offence and also cause videography of the process on mobile phone or any other electronic device." This is a proactive, technology-driven amendment to modernize criminal investigations. The provision does NOT require prior written permission from the District Magistrate (the officer-in-charge has authority to initiate this), does not restrict investigation to daylight, and requires preservation (not destruction) of forensic recordings. This section represents a significant departure from CrPC provisions, making forensic investigation mandatory for serious crimes, enhancing investigative standards.
