Update (4:30 PM EST): According to the Navy, the report of a shooting at Naval Medical Center San Diego appears to be a false alarm.
An active shooter has been reported in the area of the San Diego Naval Medical Center (NMCSD) in San Diego, CA.
The hospital provides medical care to active duty, dependents, and retirees. Facilities include a 272-bed hospital, 18 operating rooms, 2 Fisher Houses, 2 gyms, basketball and volleyball courts, and a softball field.
According to a naval spokesperson, three shots were reported to have been fired around 8:00 a.m. (local time) in the basement of Building 26, which is located in the 34000 block of Bob Wilson Drive.
According to a NBC correspondent, the building houses the wounded warrior barracks and a fitness center.
At around 8:30 a.m., two California Highway Patrol officers were seen entering the facility through an emergency room entrance near Florida Drive.
The Navy Medical Center San Diego (NMCSD) told building occupants at 8:15 AM (local time) to “run, hide, or fight” via their official Facebook page.
A California Highway Patrol officer told NBC at 9:15 AM (local time) that their responsibility at the scene is to maintain a blockade to stop traffic from entering the facility. The Navy Military Police and federal agencies have jurisdiction on the scene and have not requested help from the CHP or Chula Vista police.
All non-emergency and non-law enforcement personnel have been advised to stay away.
A law enforcement official told NBC reporter Pete Williams that an initial sweep of Building 26 found no sign that any shots were fired.
