From a New York Times story by Christina Anderson headlined “Who Is Stealing Speed Cameras From Swedish Roads?”:

The thieves strike along roads in rural Sweden, usually between midnight and 3 a.m. They employ blunt force, sometimes using a saw or driving over the cabinets that hold their targets: high-technology speed cameras.

After briefly stopping in September, the thefts have resumed, with the police investigating 160 cases in all. It can cost more than $22,000 to replace each camera and repair the damage.
