After a confrontation that halted a large part of Washington for more than five hours, a man who claimed to have a bomb in a pickup truck near the US Capitol surrendered to authorities on Thursday.

The man, identified as Floyd Ray Roseberry, parked his vehicle on a sidewalk outside the U.S. Library of Congress at about 9:15 a.m. EDT (1315 GMT) and told an officer who approached him that he had a bomb while holding what appeared to be a detonator, according to Capitol Police Chief J. Thomas Manger.

While negotiating with Roseberry, police shut down streets and evacuated surrounding buildings.

“He gave up and did not resist and our folks were able to take him into custody without incident,” said Manger.

Police did not say whether he had any explosives.

A video livestreamed on Facebook showed Roseberry, a bald white man with a goatee, speaking inside a black truck parked on a sidewalk.

“The revolution’s on, it’s here,” he said in the video, while appearing to hold a large metal cannister on his lap. “I’m trying to get (U.S. President) Joe Biden on the phone.”

His ex-wife, Crystal Roseberry, told Reuters that he had been diagnosed with schizophrenia and had threatened her with firearms in the past. She said she divorced him about eight years ago.

“He’s crazy. He pulled a gun on me and his sister, and shot at me numerous times,” said the woman.

Facebook deactivated the livestream and removed the man’s profile after about four hours.

Federal agents raided Roseberry’s home in Grover, North Carolina, during the standoff in the U.S. capital.

Neighbors said Roseberry would set off explosives in his yard and disrupt deer hunters by shooting his gun repeatedly.

“He didn’t want nobody killing no deer,” neighbor Wayne Davis told Reuters.

In Washington, the ordinarily crowded Capitol Hill area was relatively deserted, with the U.S. House of Representatives and Senate out of session.

Police blocked off roads surrounding the Capitol complex as fire and rescue trucks headed to the area. The Bureau of Alcohol, Tobacco, Firearms and Explosives said it was sending a bomb technician to support police. The Federal Bureau of Investigation also responded.

Nearby buildings, including the U.S. Supreme Court, were evacuated.

High-security fencing was erected in the area after the deadly Jan. 6 attack on the Capitol by supporters of then-President Donald Trump, but it was removed by mid-July.
