Samuel Camargo, 26, was wanted by the FBI after one of his former classmates reportedly tipped the agency off to his involvement in the riots on 6 January, as Congress convened to certify former President Donald Trump’s defeat in the 2020 elections.

Mr Camargo, who has not yet entered a plea, was arrested on Wednesday in Washington, prosecutors said. The court filing said he became “uncooperative” after initially being contacted by the FBI, when he “questioned the agent’s loyalty to the constitution before saying he had no more information to provide.”

The prosecutors said Mr Camargo fled his home in Florida on Tuesday as authorities attempted to arrest him.
