Terrorist Surrenders after US Capitol Hill Bomb Threat

A man who claimed to have a bomb in a pickup truck outside the Library of Congress surrendered to the police in Washington DC on Thursday, after hours of negotiations and evacuations of several government buildings in the area.

The police closed off several streets and sent alerts to congressional staff members, prompting evacuations.

Law enforcement officials told NBC News the suspect in the Capitol Hill bomb threat investigation is identified as Floyd Ray Roseberry.

Most, if any, lawmakers were not in the building, with the House not scheduled to return for votes until next Monday. Capitol Hill staff and Library of Congress personnel were working on-site Thursday when the evacuations began, though it’s unclear how many staffers were in the building, with many offices allowing their staff to work from home.

For many Hill staffers, the emergency alerts renewed a sense of anxiety for those who had been in the building for the Jan. 6 riots, with some campus-wide security questions still unanswered. Pipe bombs were found at both the RNC and DNC on Jan. 6 — the campaign headquarters for both parties, located near Capitol Hill — but the perpetrator was never caught.

The suspect, 49-year-old Floyd Ray Roseberry, got out of his black pick-up truck after an hours-long standoff that had led to the evacuation of the library, the Supreme Court, a House office building, and the offices of the Republican National Committee.

The U.S. Capitol Police Twitter feed warned people to "please stay away from this area."
