Police are asking for help finding a man suspected in an assault outside The Nines hotel during Portland’s last large protest.

Joseph Christian Evans, 35, is suspected of assaulting Adam William Kelly during the protest, which played out downtown in late June, according to police and court records. Video footage of the incident shows multiple people being attacked during street fights.

It’s unclear what led to the altercation or what role Evans played. The incident unfolded amid dueling demonstrations that were ultimately declared a civil disturbance and unlawful assembly.

Evans had curly, brown, shoulder-length hair and “longer” facial hair at the time, according to police. He was wearing glasses, a multicolored bandana around his neck, a black “Star Wars” t-shirt and tan pants, police said Tuesday. He has brown eyes and numerous tattoos.

Evans — who has no local address, stands 5-foot-8 and weighs 150 pounds — has a felony warrant for his arrest that’s enforceable nationwide, police said. He has previously been in New York, Tennessee, North Carolina, Utah and California, according to police.

The Portland Police Bureau’s request for help finding Evans comes days before the city’s next big political protest, which is expected to draw sizable crowds from rival political factions.

Right-wing activists from throughout the nation are planning a waterfront rally condemning anti-fascists, or antifa, and pushing to have them designated as domestic terrorists.

Counterprotesters are expected to show up in opposition.

Portland’s mayor and police chief have promised a large turnout by police and have vowed to use the full force of the law against those who commit violence and vandalism.

Police ask anyone who has information about Evans’ location to email crimetips@portlandoregon.gov.

They also said tipsters who want to remain anonymous can report information to Crime Stoppers of Oregon, which offers rewards of as much as $2,500 for information, reported to the nonprofit, that leads to arrests in unsolved felony cases.

Tipsters can submit information online, by calling 503-823-4357 or by using the P3 Tips mobile application.
