In newly unsealed documents, prosecutors allege Patriot Prayer leader Joey Gibson took numerous steps to incite a riot outside a Northeast Portland bar on May 1 as members of his right-wing group confronted their leftist antifa opponents.

The prosecution filed the court documents Aug. 12, but they were made public for the first time Wednesday after a judge last week ordered their release. According to the filings, a Portland police detective identified Gibson on video as “physically pushing” a 31-year-old woman before one of his associates, Ian Alexander Kramer, “eventually” knocks the woman unconscious with a baton.

The documents don’t specify which video the detective was referencing, but publicly accessible video on Twitter and YouTube shows the confrontation, with the action starting shortly after the 42-minute mark:

She was at the Cider Riot bar with Joey Gibson and other far-right Patriot Prayer members attacked patrons. Ian Kramer hit a woman in the head with a metal police baton knocking her unconscious and putting her in the hospital.

It appears that Gibson -- who is wearing a black T-shirt, sunglasses and a tan cap -- makes contact with the woman. But it’s unclear if that’s what the detective refers to as pushing in the prosecution documents.

Seconds later, the woman suddenly falls to the ground. A man wearing a black helmet and goggles can be seen swinging a baton, and Gibson can be seen pushing him back. The immediate aftermath was captured in this video:

The prosecutor’s office also says in the documents that the detective watched video showing 35-year-old Gibson “repeatedly challenging members of the Antifa group to fight him as he says ‘do something’ and taunts them from the sidewalk.”

Gibson is one of six people associated with his conservative, Vancouver-based group who were charged last month with the crime of riot, a felony, or other charges stemming from the clash outside Cider Riot, a bar at Northeast 8th Avenue and Couch Street.

Gibson has pleaded not guilty in Multnomah County Circuit Court, and so have defendants Christopher Ryan Ponte, Mackenzie William Lewis, Matthew Demetrius Cooper and Kramer. A sixth defendant, Russell Earl Schultz III, has a warrant out for his arrest.

The bar was hosting a gathering attended by some left-wing activists who took part in demonstrations earlier that day. But hostilities exploded when people associated with Patriot Prayer and the Proud Boys, a group that describes its members as Western chauvinists, showed up outside the bar’s patio. Police estimated there were about 15 Patriot Prayer supporters and 50 anti-fascist, or antifa, associates present.

A chaotic scene erupted, with shouting, swearing, brawling, drink-throwing, rock-throwing and people using pepper spray or mace on others.

According to the prosecution documents, Detective Christopher Traynor watched video showing Ponte shooting pepper-spray or mace at the antifa crowd. After viewing different videos taken from various angles, the detective also determined that Ponte was responsible for throwing a rock that struck a different woman than the one who was struck with the baton.

The woman gave the detective photos of her injuries, according to the documents.

In addition to riot, Ponte also has been charged with recklessly endangering another person.

The detective also said he watched video of Cooper “physically attacking members of the Antifa group, throwing objects at them, and attempting to provoke a fight” and Lewis “physically taunting members of the Antifa group.”

Read one of the unsealed documents here:

To prove the charge of riot, prosecutors must show that five or more people took part “in tumultuous and violent conduct and thereby intentionally or recklessly” created “a grave risk of causing public alarm,” according to the Oregon statute.

Gibson is the first of the six defendants scheduled to go to trial, which is tentatively set for Oct. 11.
