A retired U.S. special forces soldier faces several criminal charges over the assault of several police officers during the Capitol riot, including the throwing of a flagpole like a spear at another officer, authorities said. 

Jeffrey McKellop, 55, was arrested Wednesday and is the latest military veteran charged in the Jan. 6 siege of the Capitol. In all, he faces six federal charges.

Images of McKellop show him in a crowd wearing military-type tactical gear, including a gas mask, body armor and helmet. During a confrontation with a Washington D.C., police officer, he picked up a flagpole from the ground and shoved in the officer's face, the FBI said. 

He then allegedly threw the pole "similar in fashion to throwing a spear," according to court documents.

The officer suffered a laceration to the face, according to an FBI affidavit. 

Moments prior, the Fisherville, Va., resident clashed with three other police officers in which he allegedly assaulted them. Authorities said he also threw a bottle at Washington D.C., police and Capitol Police officers and tried to wrestle away a can of riot-control spray from another officer.

Police body cameras captured McKellop violently engaging with authorities, the FBI said. At one point, he was captured holding a "thin blue line" flag. The image signals support for law enforcement officers.
