PORTLAND, Ore. (AP) — Hundreds of people gathered in Portland for another night of protests Saturday as demonstrations over George Floyd’s killing and the presence of federal agents sent by President Donald Trump showed no signs of abating.

Crowds began to march toward the city’s federal courthouse around 9:15 p.m. A big group of demonstrators in the North Portland neighborhood also paraded by the police precinct there, which was roped off and had officers in riot gear standing outside the building.

During demonstrations the previous night federal agents repeatedly fired tear gas to break up rowdy protests that continued into the early morning Saturday. Authorities say six federal officers were injured and one person was arrested.

Demonstrations have happened in Oregon’s largest city nightly for two months since Floyd was killed in Minneapolis in May. Trump said he sent federal agents to Portland to halt the unrest but state and local officials say they are making the situation worse.

There were demonstrations for police reform and against the increased presence of federal law enforcement in cities across the country Saturday. In Seattle police declared a riot Saturday afternoon following large demonstrations and deployed flash bangs and pepper spray to try to clear crowds. Authorities made more than two dozen arrests and one officer was hospitalized with a leg injury caused by an explosive.

Late Friday, a federal judge denied a request by Oregon’s attorney general to restrict the actions of federal police.

The Federal Protective Service had declared the gathering in Portland that began Friday evening an unlawful assembly. Harry Fones, a Homeland Security spokesman, said at a news conference Saturday afternoon some people launched large fireworks, threw hard projectiles and used power tools to damage property.

Craig Gabriel, Assistant U.S. Attorney for the District of Oregon, said at the news conference that of the six federal officers who were injured, one suffered a concussion and another was taken to the hospital for burns.

He said one person was arrested for failing to comply with orders. That person was later released without charges, bringing the total number of people arrested on or near the courthouse property since early July to 60.

“It’s the very few of the crowd who come not intent on doing anything with their voice but intent on destruction and intent on confrontation, unfortunately, with federal police,” Gabriel said, acknowledging that the majority of protesters are peaceful.

Gabriel said the fence erected around the courthouse has been targeted by “violent agitators.”

“If the courthouse can stand and can have integrity and not subject to damage or attack, then the officers will go home. I think — not to be flippant — but I think it’s that simple,” Gabriel said.

Daniel Pereyo was one protester who was tear-gassed during the demonstration that began Friday. Pereyo said he had been at the nearby park watching drummers and fireworks being shot, when his face and eyes began to burn.

“It’s extremely painful,” he said. “It’s not the worst pain ever, but it is discomforting and it’s distracting.”

As the crowd dispersed, someone was found stabbed nearby, Portland police said. The person was taken to a hospital and a suspect was taken into custody.
