Sioux City, Iowa — Many people are warming up their cars on these cold winter days to melt the snow and ice off the windshields before they head out.
Sioux City Police Department spokesman, Jim Clark says that has led to a surge of stolen cars.
The unlocked cars were all stolen within a half-hour period on Wednesday. Sergeant Clark says you need to take steps to lock the car if you are going to start it and then come inside.
Clark says there was another car left running that was stolen Thursday morning.
