Authorities investigating a report of shots fired Tuesday at the Naval Medical Center San Diego said they found no evidence to support the claim after a number of sweeps inside the building.
The sitiuation unfolded quickly after the center posted a message on its Facebook page advising occupants to “run hide or fight.” Non-emergency response personnel were asked to avoid the compound at 34800 Bob Wilson Drive. The center posted that the shooter was believed to be in Building 26.
Kevin Dixon, the public information officer for the Navy, told Fox 5 San Diego that there was no evidence of a shooting after the first sweep of the building.
According to intitial reports, three shots were heard in the basement of the building, which is a combination of a gym and barrack. There are no reports of injuries.
Authorities continue to sweep the building and rows of employees were seen leaving the building with their arms raised. The reported shooter was not located.
Fox 5 San Diego reported that three nearby schools were on a temporary lockdown.
The facility has a staff of more than 6,500 military and civilian personnel, and aims to provide medical care to military service members, their families, and those who served in the past, according to its website.
"We're not taking any chances and are executing procedures we've been trained for in this kind of situation," Naval Medical Center spokesman Mike Alvarez said.
