Several people have been arrested after a May Day protest in downtown Seattle turned violent Tuesday night. Q13 Fox reports police were using pepper spray and "ball blasts," which give off a bang and a dose of pepper, to control the crowd. The protest turned violent around 7:45 p.m., with protesters throwing rocks, bottles, metal bars at officers. Police officers ordered the protesters to clear the area or face arrest. This is the second year in a row a Seattle May Day protest has turned violent, according to Q13 Fox.
