A man who walked around downtown Seattle wearing a Nazi armband was tracked down by Antifascist activists and knocked out old on the sidewalk.

According to BuzzFeed, the unidentified man was riding on a bus where witnesses say he harassed a black passenger. Anti-fascist groups then used social media to track down the man who was spotted on a street corner near downtown Seattle.

When he was confronted, a man punched him square in the face, knocking the Nazi out cold.

BuzzFeed interviewed an anonymous social media user who helped track the man down:

“I would say that we successfully identified, tracked and coordinated to neutralize a clear and present danger to Seattle,” said the user. “Whether we coordinated the actual punch or not… I, for one, applaud the anonymous hero.”
