Sgt. David Schlosser of the U.S. Park Police said Friday evening that the agency received a report of shots fired near 16th Street and Constitution Avenue, NW, between The White House and the Washington Monument, at about 9:30 p.m.
He said that shortly afterward, officers located an abandoned vehicle several blocks away on the ramp to the nearby Theodore Roosevelt Bridge.
He said police are looking at "involvement of this vehicle in the situation," but didn't know whether a weapon was recovered. He said police suspect another vehicle was involved.
Police are looking for bullet holes and haven't confirmed that shots were actually fired. He said The White House is a fair distance away and doesn't appear to have been the focus.
