In neighboring Denmark, where the annual weeklong Roskilde rock festival attended by 130,000 people wound up on Sunday, police said they had reports of five cases of alleged rape or sexual assault, which police officer Carsten Andersen described as “nothing out of the ordinary at such a big event, although every single case is too much.”
