US Capitol riot: Horned helmet rioter Jake Angeli, who calls himself QAnon Sharman, arrested by FBI

One of the more infamous Trumpers involved in the siege on the US Capitol, which killed five people, has been arrested and is facing serious charges.

Federal agents in the United States have arrested the Capitol building rioter seen wearing a horned-headdress and holding a spear during this week’s horrific and deadly rampage.

Jacob Anthony Chansley, 33, also known as Jake Angeli, who refers to himself as the QAnon Sharman, was busted Saturday, officials announced.

The shirtless Chansley — who apparently took style cues from an elk’s lodge and the film Conan the Barbarian — was identified “as the man seen in media coverage who entered the Capitol building dressed in horns, a bearskin headdress, red, white and blue face paint, shirtless, and tan pants,” Justice Department officials said in a statement.

“This individual carried a spear, approximately 6 feet in length, with an American flag tied just below the blade,” the feds added.

QAnon conspiracist and Trump supporter Jake Angeli was one of the rioters who occupied the Capitol building.

Chansley — who appears in footage from Wednesday’s chaos pumping his bicep on the dais in the Senate chamber — was charged with knowingly entering or remaining in any restricted building or grounds without lawful authority, and with violent entry and disorderly conduct on Capitol grounds.

“The fact that we had a bunch of our traitors in office hunker down, put on their gas masks and retreat into their underground bunker, I consider that a win,” Chansley, identified as Angeli, told NBC News after the riot.

Chansley, who is known as the “QAnon Shaman” or “Q Shaman,” is a diehard Trump supporter who has attended past far-right events, and is known for his support of the unfounded QAnon conspiracy theory according to MSN.

The Justice Department also confirmed Saturday the Friday arrest of Adam Christian Johnson, who was seen in a viral photo carrying off Speaker Nancy Pelosi’s lectern.

Johnson, 36, of Parrish, Florida, was charged with one count of knowingly entering or remaining in any restricted building or grounds without lawful authority; one count of theft of government property; and one count of violent entry and disorderly conduct on Capitol grounds.

Also busted Friday was Derrick Evans, 35, of West Virginia, a freshman member of the West Virginia House of Delegates. Evans streamed himself entering the Capitol with the mob on his Facebook page, shouting as he crossed the threshold, “We’re in, we’re in! Derrick Evans is in the Capitol!”
