Members of Antifa and Patriot Prayer lobbed projectiles and traded blows at times during the confrontation in the streets, which sent at least four people to the hospital and left another four in handcuffs by the time the mob dispersed. One police officer was also injured, and an additional five people were cited by the Department of Homeland Security.

Roughly 150 members of Patriot Prayer arrived in Terry Schrunk Plaza on Southwest Madison Street across from City Hall by 4 p.m., with some arriving from Vancouver on buses chartered by Joey Gibson, a right-wing candidate running for U.S. Senate in Washington State.

Across the street in Chapman Square, there were at least two times as many anti-fascist counter protesters dressed in black. Both sides heckled each other with insults and chants.

Multiple law enforcement agencies kept the groups mostly separated for the first hour, but clashes erupted after Patriot Prayer members began a march for which they had applied and received a permit.

As the scuffles continued, authorities wearing riot gear unleashed pepper spray — stun grenades that make loud noises and flashes of light — and canisters that release smoke and rubber balls, according to a news release, but said on social media that they did not use tear gas.

"Portland Police planned for today's protest so that people could exercise their First Amendment rights to speech and assembly," Deputy Chief Bob Day said in the news release.

"We seized numerous weapons early on, and interceded and separated people when necessary," he continued. "However, once projectiles, such as fireworks, eggs, rocks, bottles and construction equipment were thrown and people were injured, we ordered people to disperse."

First responders treated several people on scene, and one of the four transported to the hospital by ambulance received a "serious injury," police say.

The officer who was injured was hit by a thrown object and was transported to the hospital in a patrol car for treatment of a "non-serious and non-life-threatening injury."

Here's a list of who was arrested by Portland Police:

• Luis Enrique Marquez, 46, faces charges of first-degree theft, third-degree theft and third-degree assault after he was arrested in Chapman Square.

• Tusitala J. Toese, 22, faces a charge of fourth-degree assault after he was arrested just as the protest began in Terry Schrunk Plaza. Toese, who goes by the nickname "Tiny," apparently has returned from Samoa after members of Patriot Prayer held a "going away party" for him on June 3, which also spurred counter protests.

• Donovon Lyle Flippo, 23, faces a charge of second-degree disorderly conduct after he was arrested at Terry Schrunk Plaza.

• Matthew Reid Braddock, 37, faces charges of second-degree robbery and third-degree assault after he was arrested near Southwest Broadway and Mill Street.

Braddock remains in custody, while Toese, Flippo and Marquez were booked and released, according to jail records.
