In the German press, "southerner" is a term generally used to refer to Turks and Arabs:
According to the current investigation, the young man was on his way home at 4am. At the corner of Dammstraße and Fleethörn he met two men, who demanded his cash and mobile phone.
As he turned and ran, the assailants stabbed him in the shoulder and thigh. The victim managed to flee on foot across Hofstraße and make it inside his flat, where he tended to his bleeding injuries and alerted the emergency services.
The man, who had been drinking, was taken to the Uniklinikum where his stab wounds were treated.
The man said that the perpetrators were two Southerners. They were about 1.70 meters tall and 20 to 25 years old.
As one of the commentators at PI points out, both the thigh and shoulder contain major arteries - this is really a case of attempted murder being treated as attempted robbery and assault.
One wonders how many other such cases such as this go unremarked upon as they're downgraded in seriousness across Germany and the rest of Europe each evening.
