Portland, Oregon — A riot was again declared by authorities Sunday night in Portland when protesters marched to a police union building, blocked a road and set dumpster fires as officers work to quell nightly unrest in Oregon's largest city. The protest was over almost as soon as it began outside the Portland Police Association building - the same building where protesters were dispersed after a fire was started inside the offices the night before.
Demonstrators Sunday night marched to the building from a park a few blocks away. The road was blocked with fencing, and flames were seen rising from dumpsters in the middle of the street.
The Portland Police Association is a labor union that represents members of the Portland Police Bureau.
Police and state troopers forced a couple of hundred protesters away from the building, reports CBS Portland affiliate KOIN-TV.
While demonstrators were being dispersed, commercial-grade fireworks were thrown at officers, injuring two, police said. The department released photos of the officers' injuries, including a photo of a face covering that "partially melted" from the firework. The officers were treated at the scene.
Groups of people broke off, KOIN said. Some gathered in Kenton Park, which provoked another announcement from police that, "This is still a riot."
Some protesters returned to the union building after officers cleared the area. Police said the road was again blocked with fencing and small fires broke out in the street. Multiple people were arrested, police said, but details weren't immediately available.
KOIN reporters saw police arrest Demetria Hester, the leader of Moms United for Black Lives.
Since George Floyd was killed in Minneapolis, protests have occurred nightly in the city for more than 70 days.
Demonstrations this past week have been violent. Many in the city had hoped for calm after federal agents withdrew more than a week ago.
Three officers were hurt, including two who were taken to a hospital, during the efforts to clear the crowd of several hundred people outside the union building late Saturday. The two hospitalized officers have since been released. Nine people were arrested during the protest, police said in a statement.
Police arrested 24 people during demonstrations overnight Friday after, they said, people defied orders to disperse and threw rocks, frozen or hard-boiled eggs and commercial-grade fireworks at officers.
Some demonstrators filled pool noodles with nails and placed them in the road, causing extensive damage to a patrol vehicle, police said. Oregon State Police worked with Portland officers to clear the protesters.
The gatherings this past week had been noticeably smaller than the crowds of thousands who turned out nightly for about two weeks in July to protest the presence of U.S. agents sent by the Trump administration to protect the federal courthouse downtown.
The Portland Police Association building is located about 5 miles north of the federal courthouse.
