Several governmental buildings in Washington, D.C., were evacuated Thursday morning due to what Capitol Police call "an active bomb threat investigation" after a man drove a pickup truck onto a sidewalk.
The bomb threat suspect has surrendered and is in police custody, a law enforcement source told ABC News Thursday afternoon.
The suspect had told responding officers he had a bomb, and responding officers said he had what appeared to be a detonator in his hand, Capitol Police Chief J. Thomas Manger said at a news conference.
Authorities are also investigating a video posted to Facebook that purports to have been posted by the man in the vehicle.

The Cannon House Office Building, a congressional office building, was evacuated via underground routes. The Library of Congress and Supreme Court building were also evacuated. Both the Supreme Court and Congress are on recess.
Messages have been sent to congressional staffers asking that they "remain calm and relocate to Longworth House Office Building using the underground tunnels."
Senate staff were asked in a message to "remain clear of the police activity" and to "please move indoors" if they were outside on Capitol grounds.
The FBI said it was responding. The White House is monitoring the situation and is receiving updates from law enforcement, according to an administration official.
This is a developing story. Please check back for updates.
