A significant security breach occurred in Mumbai’s Navy Nagar area when an unidentified man, impersonating a naval officer, managed to steal an INSAS rifle and 40 live rounds from a junior sailor on duty. The incident took place on September 6, 2025, when the impersonator approached the sailor, claiming to be his replacement. After the sailor left his post to return to his accommodation, he realized the deception and reported the theft, spurring an immediate search operation by the Indian Navy and Mumbai Police, alongside the involvement of multiple investigative agencies. The ease with which the guard was misled has raised serious concerns regarding security protocols within military installations, prompting a Board of Inquiry to investigate the circumstances leading to this alarming incident. Investigators are currently examining CCTV footage and other leads to identify the suspect, highlighting potential procedural vulnerabilities that need to be addressed. This incident underscores the necessity for stricter verification processes and advanced security technologies, such as biometric access, to prevent future breaches and enhance the overall security framework of sensitive military areas.
