Two of them remained peaceful, but the others resulted in “property damage and arrests,” he said.
A group of about 150 people converged on the ICE building in the South Waterfront neighborhood Wednesday evening around 9 p.m., Allen said.
Some demonstrators were carrying pepper ball guns, fireworks, shields, rocks and “electronic control weapons similar to Tasers.”
Federal law enforcement officers deployed “crowd control munitions,” Allen said, though he did not say what kind, deferring to federal officials. Portland Police did not deploy CS gas (commonly referred to as tear gas), Allen added.
Allen said that Portland Police were in the surrounding neighborhood and “some arrests were made.”
8 arrests made after vandalism at Democratic Party headquarters
The demonstration at the ICE building followed another earlier in the day, when a crowd of about 150 people gathered at Revolution Hall before marching to the Oregon state Democratic Party headquarters.
The group then left Revolution Hall and marched to the Democratic Party headquarters, where some demonstrators “smashed windows and vandalized the building,” Allen said.
At one point the crowd “showed aggression by swarming officers and throwing objects,” Allen said.
At least 8 people were arrested on various charges, including felony criminal mischief, possession of a destructive device and rioting, Allen said.
“This is not the first time our building has been vandalized during the past year — none of the prior incidents have deterred us from our important work to elect Democrats up and down the ballot, and this one will be no different,” the statement said.
Federal courthouse in Seattle also damaged
Police in Seattle also reported vandalism to several buildings in its downtown area Wednesday night, including at a federal courthouse.
The Seattle Police Department shared photos on Twitter, saying “multiple windows” were shattered at the William Kenzo Nakamura Courthouse, used primarily by the Ninth Circuit Court of Appeals.
Several arrests were made, police said, including some for property damage and assault. Another man was arrested in connection to a burglary investigation at the Starbucks.
