Officials lifted a lockdown at Walter Reed National Military Medical Center in Maryland on Wednesday after several hours investigating a bomb threat hoax.
Officials said security personnel responded after they received an anonymous call at 8:45 a.m. stating there was a bomb at or near Building 10 in the Naval Support Activity Bethesda, which houses the hospital. Building 10 is the hospital’s main lobby, WTOP reported.
The base went into lockdown shortly after 9 a.m., and all personnel were ordered to shelter in place. All gates to the facility were closed to non-emergency traffic, and officials asked the public to avoid the area. K-9 teams were sent in to clear buildings.
Around the time of the lockdown, officials also initially said that there was also an active shooter threat. About an hour later, they said there was no longer an indication of a shooter.
Walter Reed tweeted shortly before 10 a.m. that a “hazard” exists at the hospital and told people to shelter in place. It also said all appointments were canceled for the rest of the day.
At 1:30 p.m., the hospital said it resumed normal operations after receiving the “all clear” from officials.
