D.C. Police Report 'No Evidence' of Shooter at Walter Reed Hospital

Washington, D.C. police reported an "all clear" Monday following a report of an alleged gunshot heard at the Walter Reed National Medical Center in the nation's capital.

Police reportedly conducted a three hour search following reports of a gunshot heard on the hospital's campus before declaring that there was "no evidence" of any firearm discharge.

"Walter Reed UPDATE: Police operations are complete, there is no evidence of a firearm discharge. Normal operations expected to resume soon," the D.C. police said in a statement. 

A statement released by the Navy indicated that the hospital, one of the largest military hospitals in the nation, went into lockdown for three hours following the "unconfirmed" reports of a shooter.

"All base personnel are sheltering in place as a result of unconfirmed reports of an active shooter," the Navy's statement reported.

"DOD Security Force, NIH Police Force and County EMS and Medics have responded and searching the area," the statement added.

The false reports of gunshots come shortly after reports of a gunshot heard in the Washington Navy Yard last week that caused the military compound to go into lockdown mode for several hours.

"A call was placed from a building inside of the Washington Navy yard for possible sounds of gun shots around 0729 AM - a subsequent request was made to partner law enforcement agencies for assistance," the Washington D.C. police department said in a statement regarding last week's Washington Navy Yard false alarm, adding "At this time we have completed our search of the building and have found no evidence of a shooting or injured personnel."
