New figures released by the German federal government show that 53% of the 1,087 suspects in 751 recorded gang rapes last year were foreign nationals, despite non-German citizens making up less than 17% of Germany's population.
The cases involved 772 victims, of whom 619 (80%) were German citizens, including 565 women and 54 men.
The largest groups of suspects by nationality were Syrians (110), Afghans (64), Iraqis (46), and Turks (44).
The government data also shows that 72% of solved cases involved suspects who were already known to police.
