In August 2026, police arrested a 42-year-old man in Switzerland for a life-threatening assault that took place in Dortmund, Germany, in November 2025. The attack followed a dispute in a pub regarding the historical origins of the Celts versus the Albanian people.

The victim, a 51-year-old man, sustained severe head injuries and has remained partially paralyzed, requiring constant care. The arrest was made possible after the case was featured on the television program ‘Aktenzeichen XY… Ungelöst’, which led to an anonymous tip and other investigative leads. The suspect has been transferred to Germany as the prosecutor’s office continues its investigation.
