Police in the city of Portland said they fired crowd control munitions and tear gas on Wednesday night to break up a gathering of about 200 people who threw rocks, lit fires and vandalized a U.S. immigration agency building.
Law enforcement officials had declared a riot for a second successive night, calling a protest near the Immigration and Customs Enforcement (ICE) office an “unlawful assembly.”
Federal officers fired pepper balls and set off a few smoke devices, the Oregonian newspaper reported earlier.
Protests against racism and police brutality have swept the United States since the death on May 25 of George Floyd, a 46-year-old African-American man, after a white police officer knelt on his neck for nearly nine minutes.
The Portland protests are among those that have erupted occasionally in arson and violence, with federal officers sent into the northwestern city repeatedly clashing with crowds targeting its federal courthouse.
Wednesday’s protest began in the Elizabeth Caruthers Park before demonstrators marched toward the ICE building.
“All persons near SW Bancroft St and SW Bond Ave must disperse,” police had said on Twitter, warning the marchers they faced arrest and the use of tear gas, crowd control agents and impact weapons if they did not comply.
