Reports of an active shooter at the US Army Naval Base in Port Hueneme, Ventura County, California, prompted a lockdown and shelter-in-place orders. Initial reports indicated that the shooter was inside the medical building, causing panic among personnel. However, approximately 45 minutes later, authorities confirmed that the threat was false, and the all-clear was issued. The base's Facebook statement clarified that the incident was a false alarm, and all gates are now open. Port Hueneme is located northwest of Los Angeles along the Pacific Ocean. No injuries or fatalities have been reported. The incident involved a temporary lockdown, which was subsequently lifted after the threat was deemed unfounded.
