Prosecutors have already filed charges against several people who were arrested during the protests. In all, 17 people were arrested after the "anti-capitalism" demonstration turned violent, with protesters pelting police with rocks and bottles and police firing flash-bang grenades and pepper spray.
Several dozen protesters, many using bandanas to cover their faces, began clashing with police in downtown Seattle around 7 p.m., hours after a peaceful immigrant-rights march ended.
The march wound its way downtown on Pike Street towards the downtown retail core, where demonstrators began shoving and attacking reporters as they provided live on-air reports from the event.
Shortly after that, demonstrators ignited a smoke device, spewing orange pinkish smoke throughout the block.
After demonstrators began damaging property, throwing fireworks and rocks at officers, police formed a line to prevent the marchers from moving any further into the retail core or on to the Interstate 5 on-ramps.
Police ask anyone with information about the eight suspects to call (206) 233-2666.
