WASHINGTON (KABC) -- A man who drew what appeared to be a gun and pointed it at officers at the U.S. Capitol Visitor Center was shot by police on Monday, authorities said.
Police said the suspect entered the center through the north street entrance. He was transported to a local hospital to undergo surgery. The suspect's condition was not immediately known. Officials said the suspect has frequented the Capitol grounds before.
While authorities did not release the suspect's name, sources told ABC News the suspect was identified as Larry Dawson of Tennessee.
Dawson was issued a "stay away order" by D.C. Superior Court in October, ordering him to keep away from the Capitol grounds, court documents show.
The D.C. Police Department called it an isolated incident and said there was no active threat to the public.
The Associated Press earlier reported that a Capitol police officer was shot, but not seriously wounded. However, later reports from Capitol officials indicated there was no injury to any law enforcement officers.
A female bystander suffered minor injuries from shrapnel, but she was expected to be OK.
Police said they believe this was an act of a single person, describing the incident as a criminal act. A weapon was collected at the scene.
Authorities located the suspect's car on Capitol grounds and planned to serve a search warrant to seize the vehicle.
The event unfolded with Congress on recess and lawmakers back in their districts. The U.S. Capitol was on lockdown for about an hour and the White House also was briefly locked down.
The shooting occurred in the Visitors Center of the sprawling Capitol Complex. Staffers, reporters and others were told to "shelter in place" and not allowed to leave their offices.
Capitol office buildings and the Capitol itself were re-opened for business about an hour after the initial reports of gunfire. The Visitors Center where the shooting occurred remained closed as the incident was being investigated.
Visitors were being turned away from the Capitol as emergency vehicles flooded the street and the plaza on the building's eastern side. Police, some carrying long guns, cordoned off the streets immediately around the building, which were thick with tourists.
Traffic was jammed in the vicinity, but despite the obvious emergency the scene was relatively calm. A work crew on the north side of the Supreme Court, across the street, was asked to stop work and move away from the building as a precaution.
