A man who claimed to have a bomb in his pickup truck in front of the Library of Congress has surrendered, ending an hours-long standoff Thursday.
The suspect — identified by authorities as Floyd Ray Roseberry, 49, from Grover, N.C. — is now in custody.
"He gave up, did not resist, and our folks were able to take him into custody," U.S. Capitol Police Chief J. Thomas Manger said Thursday. "We don't know what his motives are at this time."
Manger said police negotiated with Roseberry by writing on a whiteboard. Eventually police used a robot in an attempt to give him a phone to communicate with, but Manger said Roseberry declined to use it. Manger said shortly afterward Roseberry got out of the vehicle and he was taken into custody without incident.
The truck has been removed from the scene. The U.S. Capitol Police did not find a bomb in the vehicle, but said that "possible bomb making materials were collected from the truck."
Manger said that Roseberry's mother had recently died and that according to his family, "there were other issues that he was dealing with."
Facebook removed the suspect's profile and deactivated his livestream
Earlier Thursday, law enforcement officers from Cleveland County, N.C., as well as federal law enforcement officials went to Roseberry's residence, said Philip Todd, chief deputy of the Cleveland County Sheriff's Office.
"As far as I know, the FBI has interviewed the wife, and she is cooperating," Todd told NPR's Carrie Johnson.
Several hours after the report of the incident, Facebook said it had deactivated a livestream, purportedly of the suspect in his truck.
"Not only deactivated the livestream, but we also removed his profile from Facebook and are continuing to investigate," Andy Stone, director of policy communications at Facebook, said on Twitter.
In at least one of the videos, a man can be seen making anti-government remarks as well as saying he had ammonium nitrate in his truck's toolbox.
Lawmakers are mostly away from Washington for the August recess
Manger told reporters that the man drove a black pickup onto the sidewalk in front of the library's Thomas Jefferson Building at 9:15 a.m. ET and told an officer he had a bomb. The officer said the man had what appeared to be a detonator in his hand.
The bomb threat came as Congress continues to investigate the Jan. 6 insurrection at the U.S. Capitol, when a mob of demonstrators supporting then-President Donald Trump stormed the building.
As a result of the threat, several streets in the area were closed as well as nearby buildings, including the U.S. Supreme Court and Congress. The FBI said its Washington Field Office responded to the incident, along with agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives.
Neither the House of Representatives nor the Senate is in session, and most lawmakers are not in their offices.
