A heavy metal festival in Wacken, Germany got fired up on Friday, but not from the show. Unknown perpetrators set the portable toilets on fire.
Authorities had to rescue 12 people sleeping in nearby tents, a police spokesperson said, adding that eight people were taken to the hospital for smoke inhalation.

Police believe the fire was arson and the festival organizers have set a €1,000 reward in exchange for the identity of the homegrown pyrotechnics artist.
Some 70,000 metalheads are rocking out to 70 hard rocking bands at the sold-out Wacken Open Air festival in the northern German state of Schleswig-Holstein. Iron Maiden is headlining the self-proclaimed world's largest metal festival, which invades the tiny town of just 1,900 each year.
