Law enforcement intervened in a march on Friday when a group of demonstrators began breaking windows in the downtown area. Officers responded by establishing a perimeter around the crowd and announcing that the protesters were being detained.
According to the Portland Police Bureau (PPB), some of the demonstrators refused to comply and locked arms in an attempt to prevent officers from carrying out their orders. Around 100 people were identified and photographed as part of an investigation into the criminal activity, before being released.
Officers discovered a variety of weapons left behind by protesters inside the perimeter, including a crowbar, hammers, bear spray, a high-impact slingshot, and knives.
