Protesters on Capitol Hill hurled a rock through a police-car window Saturday night, injuring an officer. The group also smashed windows at a business on 12th Avenue, according to the Seattle Police Department.
The officer was treated by a medic at the scene.
The group gathered at Seattle Community College late Saturday evening before marching on Broadway.
The violence started at about 11 p.m., when one of the demonstrators threw paint at a Seattle police vehicle, police said. After police halted the group at 12th Avenue and Pike Street, demonstrators began running through the Pike-Pine corridor. Officers were unable to locate the specific individuals who committed the crimes. No arrests were made.
