Slider crime is a type of theft where a thief quickly sneaks into an unlocked car to steal valuables or the vehicle itself. It is called "slider crime" because the thief slides into the car unnoticed while the driver is distracted, such as while pumping gas or paying for a purchase. Slider crime is a growing threat across the United States, and police departments are warning the public to be aware of this type of crime. It is important to always lock car doors and windows, even when leaving the car for a short period of time, and to be aware of your surroundings when pumping gas or making purchases.
