A North Carolina man has been charged for his involvement in the U.S. Capitol attack on January 6th, according to court documents.

Stephen Horn, 51, from Wake Forest, N.C. turned himself into authorities on Feb. 24 and faced an initial court appearance in Raleigh on Friday.

Horn is charged with at least four separate counts that includes knowingly entering or remaining in any restricted building or grounds without lawful authority; disorderly and disruptive conduct on Capitol grounds; violent entry and disorderly conduct on Capitol grounds; Parading, demonstrating or picketing in a Capitol building.

According to court documents, two people say they recognized Horn from an Instagram post by The New York Times and called the FBI to identify him.

Investigators said Horn admitted to being inside the Capitol and confirmed wearing a helmet and standing on a monument with a cellphone, which is the exact pose from the photo provided by the Times.

Horn’s Facebook account showed several statements about being in the Capitol on Jan. 6 during the attack in Washington D.C., and he also made a live video recording while inside the Capitol.

Horn is the sixth person from North Carolina to be arrested in the violent Capitol siege.
