PORTLAND, Ore. (AP) — Seattle police say five people were arrested in May day protests downtown.

Seattle police tweeted Monday night that the five people ranged in age from 19 to 51 years of age. The arrest charges included theft, obstruction, unlawful possession of a weapon and attempted assault.

Olympia Police Chief Ronnie Roberts said Monday night that nine people were arrested in connection with a May day protest turned riot and that all were booked on a felony riot charge.

Roberts says rioters hit nine police officers with rocks or marbles flung out of sling shots but no one was seriously injured thanks to police helmets and other gear.
