A delivery van belonging Donut Delite began its illegal odyssey in Moline, Ill., and ended with a police chase in central Iowa, Quad Cities (Ill.) Online reported.
The driver left the van running while making a delivery at Trinity Medical Center in Rock Island Thursday before dawn. When he couldn’t find the van, the driver called police, who issued an all-points bulletin.
A county sheriff in Iowa spotted the van, called reinforcements and a high-speed chase ensued, with speeds topping 100 mph, QConline.com reported. The driver was arrested at gunpoint after officers rammed the van with a vehicle.
The Donut Delite van was returned to its owners in Moline Thursday afternoon – contents uneaten.
