Police used flash bang devices and pepper spray to disperse Seattle protesters after the largely peaceful demonstrations descended into chaos.
The city saw its ninth consecutive day of George Floyd protests on Saturday.
The mayhem in Seattle’s Capitol Hill neighbourhood followed a large, peaceful demonstration earlier in the day with medical workers demonstrating against racism and police brutality.
It also came a day after Mayor Jenny Durkan and Police Chief Carmen Best imposed a 30-day moratorium on the department’s use of one kind of tear gas.
KING-TV reported that a small group of protesters started throwing objects at officers about 7.30pm on Saturday night.
Police ordered the crowd to move, then used incendiary devices.
After police were severely criticised by protesters and public officials alike for using tear gas and pepper spray to disperse largely peaceful crowds, Ms Durkan and Ms Best said Friday outside groups would review and update crowd-control policies, including the use of pepper spray and deadly force techniques such as neck and choke holds.
She and the mayor added that the ban on one kind of tear gas known as CS could be extended if groups need more time for policy review.Earlier in the day, thousands of doctors, nurses and others marched from Harborview Medical Center to City Hall. Many wore lab coats and scrubs.
The recent demonstrations in Seattle have been among the largest the city has seen in years.
