A man photographed in a fur hat topped by horns during the mayhem at the US Capitol building has been taken into custody, officials said.

Jacob Anthony Chansley, more commonly known as Jake Angeli, is charged with knowingly entering or remaining in a restricted building or grounds without lawful authority, and violent entry and disorderly conduct on Capitol grounds in Washington.

Chansley is among dozens of Donald Trump supporters arrested in the wake of the Capitol invasion by a large mob enraged over Mr Trump’s election loss, forcing legislators to halt their voting to affirm president-elect Joe Biden’s victory and go into hiding.

Separately, the man photographed grinning as he carried away US house speaker Nancy Pelosi’s lectern has also been charged following the rioting that left five people dead.

Adam Johnson, 36, of Parrish, Florida, was arrested on Friday night on a federal warrant and is being held without bail in Pinellas County, Florida, according to jail records.

Johnson is a married father-of-five who was quickly identified on social media by local residents as the man smiling as he walked through the Capitol rotunda carrying Ms Pelosi’s lectern, The Bradenton Herald reported.

Before being deleted or taken down, Johnson posted on social media that he was in Washington, DC, during Wednesday’s riot. His content included disparaging comments about the Black Lives Matter movement, according to The Bradenton Herald.

The rioters took over the house and senate chambers and smashed windows on Wednesday. Some waved Confederate flags.

By Saturday, prosecutors had filed 17 cases in federal district court and 40 others in the District of Columbia Superior Court for a variety of offences, ranging from assaulting police officers to entering restricted areas of the US Capitol, stealing federal property and threatening members of congress.

Prosecutors said additional cases remained under seal, dozens of other people were being sought by federal agents and the US attorney in Washington vowed that “all options were on the table” for charges, including possibly sedition.
