 Arklöv was arrested a short time after the fighting ceased, while walking over the Bosniak border while drunk and was accused of war crimes, including torturing pregnant Bosniak prisoners in concentration camps in Gabela camp, Dretelj camp and Grabovina.The crimes were severe and he had, among other things, forced a woman to say "Allahu akbar" before shoving his rifle into her mouth, whipped prisoners with a Waffen-SS belt, abused and tortured pregnant girls, as well as having beaten young men and broken their arms and legs.Prisoners in the camps called Arklöv "the Black Devil" because of his black fascist uniform and skin-colour.
