Malmö, the third-largest city in Sweden, is currently in the thralls of a bizarre epidemic: Car fires. According to local news reports, officials in the southern municipality have recorded more than 70 vehicle burned since the beginning of July. Stranger still, nearly all of them have been deemed intentional.

This is a legit arson spree, and a prolific one at that. Consider the week of August 1-8, when 23 cars burned up. Or Friday, when a staggering 16 vehicles were torched overnight. The attacks have spread out over a number of areas, though Rosengård, a rough part of town, has gotten the brunt of the damage.
