PORTLAND, Ore. — Two men were arrested Thursday morning in connection with a large fight on May Day outside Cider Riot Bar in Northeast Portland.

The two suspects, 24-year-old Matthew D. Cooper and 50-year-old Russell E. Schultz, were arrested on active warrants by The U.S. Marshals Service for riot. Cooper was also named in an earlier indictment.

Members of the right-wing group Patriot Prayer and left-wing Antifa brawled in the streets outside the bar located near Northeast 8th Avenue and Couch Street. The fight between approximately 60 people marked a violent end to an otherwise peaceful May Day in Portland.
