The Navy has given the 'all clear' at the complex housing the Walter Reed National Military Medical Center in Bethesda, Maryland, after reports of a single gunshot turned up no evidence of a shooting, casualties or injuries.
A call came in at 10:48 a.m. Monday reporting that a shot had been fired. Employees were directed to shelter in place while law enforcement swept the area.
Police say they have not yet confirmed a shot was fired, but employees were immediately told to shelter in place.
The Associated Press reported the 911 caller reported hearing the alleged shot inside Building 1.
The Navy said in a statement before lunchtime on Monday that Defense Department Security Force, National Institutes of Health Police Force and Montgomvery County Emergency Management Services responded and were searching.
At around 2 p.m., Walter Reed announced normal operations were expected to resume shortly.
The report of gunfire comes less than a week of a similar report, which also turned up no evidence of a shooter or victims, at the Washington Navy Yard.
