Dresden police are searching for a man - described as sporting a Hitler mustache and wearing a Nazi-style helmet emblazoned with a swastika - who assaulted an Afghan immigrant on a sledding hill in eastern Germany.
Police said Tuesday the man approached two Afghan men, aged 21 and 26, on Saturday in Geising, south of Dresden. Witnesses say the attacker insulted them, and then hit the younger man on the head, knocking him to the ground.
After passers-by intervened, police say the man showed the stiff-armed Nazi salute, then fled the scene.
The man, who is being sought on charges of assault and the display of banned symbols, is described as strongly built, about 25-30 years old, with a shaved head.
Police are appealing to the public for any information.
Meanwhile, support for German Chancellor Angela Merkel's conservative bloc fell 2.5 percentage points to 32.5 percent, its lowest level since the 2013 election, an INSA poll in Germany's top-selling Bild newspaper showed on Tuesday.
The poll also put the right-wing Alternative for Germany (AfD) up one point at 12.5 percent. INSA tends to put the AfD slightly higher than most other polling institutes.
Bild gave no reason for the drop but Merkel's popularity and that of her conservative bloc has been falling since the refugee crisis.
