Police say the American man, 41, endured minor harms after he made the solid arm motion around 8.15am on Saturday in downtown Dresden.
He was punched by a bystander, who at that point fled the scene and is being looked for by police for causing real damage.
It comes only seven days after two Chinese visitors were captured taking photographs of themselves doing the salute before the Reichstag building.
PSA to vacationers: Don’t do a Nazi salute in Germany. Try not to do it anyplace truth be told. Clearly this hasn’t broke through to a few people.
Dresden police would not give the Americans name or main residence for security reasons.
In Germany, it is unlawful to show any Nazi images or mottos, including giving the ‘Heil Hitler’ salute.
On August 5 two Chinese voyagers were discovered taking photographs of themselves making the motion before Berlin’s Reichstag building.
The men, matured 36 and 49, were spotted by police close to the German parliament, taking photographs playing out the raised arm signal.
Officers said in an announcement that the visitors were addressed at an adjacent area yet later discharged in the wake of leaving a security store of £450 each.
