PORTLAND, Ore. -- Police investigators continue to seek tips from the public regarding several people wanted for assaults during the violent clash between far left- and right-wing protesters in downtown Portland.
The June 29 demonstrations turned into shouting matches and fist fights. Three people were arrested, but police later released multiple photos of wanted assault suspects.
On Wednesday, police released more photos of a male suspect with blonde hair.
Anyone with information about the suspect is asked to call Portland police.
The clash received national attention after conservative writer Andy Ngo said on Twitter he went to the emergency room after an attack by members of anti-fascist groups.
Police closed Pioneer Courthouse Square after they said demonstrators threw eggs and milkshakes at officers. Police said they were informed that some of the milkshakes contained quick-drying cement, a claim many have said is not true and the bureau said was based on reports, although not confirmed.
Portland Mayor Ted Wheeler condemned the violence amid criticism from the police union.
