Portland police detained a crowd of at least 100 protesters at a demonstration Friday night, minutes after the group began marching in the street and some began breaking windows, police said.
The march began after 9 p.m. along a street in the Pearl District, and officers told the group that the street was open to traffic, according to police. When some of the demonstrators began breaking windows, officers “created a perimeter around the group,” police said.
“To everyone inside the perimeter: you are being detained for investigation of a crime. You are not free to leave,” Portland police said on Twitter.
As officers formed the perimeter, some people on the outside threw rocks and cans of beer at officers, who used pepper spray, police said.
The mass detainment appeared to an example of kettling, a police tactic of surrounding a crowd and containing people within a perimeter, the Oregonian/Oregonlive.com reported.
Police charged 13 people, including one person suspected in window vandalism and two people carrying firearms, wearing body armor and helmets, according to a press release. Police said demonstrators left behind various items, including a crowbar, hammers, bear spray and knives.
According to videos of the event posted to social media, the group chanted slogans critical of cops and “No borders! No nation! Abolish deportation!”
The mass detentions marked the second night in a row that police responded forcefully to protesters in Portland, the Oregonian/Oregonlive.com reported. According to the newspaper, federal officers used tear gas on a group of “a few dozen protesters” who had gathered at the downtown courthouse. Some of the protesters had participated in demonstrations earlier that day against an oil pipeline, the newspaper reported.
Portland has been the site of frequent protests, many involving violent clashes between officers and demonstrators, ever since the police killing of George Floyd in Minneapolis in May. Over the summer, there were demonstrations for more than 100 straight days.
In January, a group of protesters carrying signs against President Joe Biden and police marched in Portland on Inauguration Day and damaged the headquarters of the Democratic Party of Oregon, police said.
Mayor Ted Wheeler has decried what he described as a segment of violent agitators who detract from the message of police accountability.
