Bomb threat suspect in DC surrenders after hours-long standoff

A standoff between police and a bomb threat suspect in Washington, D.C. has ended after several hours following the suspect's surrender, according to the Associated Press.

The "active bomb threat investigation" prompted the evacuation of several buildings in D.C., including the Library of Congress, the Supreme Court and Cannon House Congressional Office Building

The Associated Press reports that the situation began when police pulled over a black pickup truck because it had no license plates. The driver, identified by the AP as Floyd Ray Roseberry, 49, of Grover, North Carolina, reportedly told officers there was a bomb in the vehicle, prompting the massive police response.

Police officials confirm that an officer believed the suspect was in possession of a detonator. That began several hours of negotiation before the suspect's surrender.

At a noon ET press conference, police officials said they "don't know what (the suspect's) motives are at this time."

The AP also reports that a Facebook Live video, purportedly taken by the suspect, surfaced online as police continued their negotiations. In the video, the man, sitting in a car, made anti-government threats and called on President Joe Biden to resign.

The FBI's Washington Field Office and the Bureau of Alcohol, Tobacco and Firearms also responded to the situation.

The incident comes just over six months after thousands of Trump supporters stormed the U.S. Capitol in a massive security breach. Fencing that had been put up following the riots was removed this summer.

Both Congress and the Supreme Court are currently on summer recess.
