A man who was reportedly walking around downtown Seattle instigating fights while wearing a swastika armband was punched in the jaw and knocked unconscious by a passerby on Sunday afternoon.
The incident was captured on video and posted on the Reddit website.
Police said they were notified of the man's activities at around 4 p.m. They found him about five minutes later lying on the sidewalk near 3rd Avenue and Pine Street, said Jonah Spangenthal-Lee of the Seattle police.
The man admitted to police he had been struck but declined to discuss the incident any further. He then removed his armband and walked away from the scene, Spangenthal-Lee said.
No witnesses were found to make a report about the incident.
The video posted to Reddit shows the man with the armband talking to someone wearing a gray hooded sweatshirt and a white ballcap. The man in the sweatshirt then punches the man with the armband in the jaw, knocking him out cold.
Bystanders can be heard saying, "Whoa - yeah!" before scattering and leaving the scene.
Hours before, an anti-fascist Twitter account had shared a photo of a man riding the bus in Seattle with a Nazi armband on his right arm.
