An armed man was arrested Monday after driving to a security barricade outside the U.S. Capitol, prompting a police investigation into why he came to the heavily protected complex and temporarily shutting down part of the Capitol grounds.
Authorities have not identified the suspect or announced any charges.
Police remained at the scene Monday afternoon, where officers were seen removing items from a Ford Bronco parked diagonally in front of the barricade.
From a distance, the items appeared to include water bottles and other belongings.
A dog that had been inside the vehicle was removed safely and taken away in an SPCA vehicle.
The North Barricade remained closed as the investigation continued.
