A 15-year-old Afghan boy has been arrested suspected of fatally stabbing a German girl of the same age during an argument on Wednesday, the prosecutor in Landau in southwest Germany said, ruling out a terrorist motive.
The confrontation took place in a grocery store and the Afghan teen was arrested following descriptions given by passers-by to police.
It was not known whether the suspect was a refugee.
The German teenager died later Wednesday afternoon in hospital from her wounds.
The girl had entered the store with a companion, who was not the suspect, the prosecutor said in a statement.
