One witness reported hearing gunshots Tuesday at a U.S. naval medical facility in California, but an initial investigation found no sign of a shooting, the military said.
The Naval Medical Center in the city of San Diego was locked down after three gunshots were reported in one of its buildings, prompting authorities to sweep the facility and surroundings.
"First responders and Navy working dog units have conducted an initial top down inspection of the building and have not located any casualties or evidence of a shooting having taken place," Navy spokesman Scott Sutherland said in a statement carried by local media.
"There is a secondary, more thorough floor by floor inspection taking place at this time. The medical facility remains on lockdown and a shelter in place order remains in effect," he added.
Earlier in the day, the medical center posted on its Facebook page that a possible active shooter was reported in the facility and encouraged all occupants inside to "run, hide or fight".
Three nearby schools were also briefly locked down as a precaution, according to local media.
The medical center "has eight clinics for active duty personnel and nine primary care sites for their family members", according to its website. The center says it has a staff of more than 6,500 people, including military and civilian professionals.
