Naval Medical Center San Diego (NMCSD) posted a warning on social media after an active shooter was seen in one of the military hospital’s buildings.

“**!ATTENTION!** An active shooter has just been been reported in building #26 at Naval Medical Center San Diego. All occupants are advised to run, hide or fight. All non-emergency response personnel are asked to stay away from the compound, located at 34800 Bob Wilson Drive, San Diego, CA 92134.”

The entire military hospital went into lockdown, and the nearby San Diego Zoo, local schools and another navy base also locked down.

Here’s the timeline we know so far:

– 8:15 am: Shots were alleged fired within Building #26.

– 8:30 am: Police cars swarm the facility.

– 8:45 am: SWAT truck arrives at military hospital.

– 9:08 am: Hospital releases update saying that the 200 or so children at its childcare center, which opens at 5:30 every morning, are safe.

About 6,500 military, civilian, contractor and volunteer personnel work at NMCSD. There have been no reports of injuries or casualties


The shooting at the military hospital may have been a false alarm.

A Navy official told the Los Angeles Times that no evidence of a gunman as been found in Building #26.

“Apparently someone said they heard three shots in the basement of Building 26. Maybe they did or not is not the point, that’s what they reported so that’s why we responded accordingly,” Navy spokesman John Nylander said. “We haven’t gotten any reports of any injuries.”

Law enforcement is currently sweeping the building a second time. It’s still unclear whether this was an honest mistake or a hoax.

SECOND UPDATE: According to the Navy, the coast is clear. Either the situation was a mixup, or a ill-conceived hoax.
