Police say a 3-year-old girl sitting in a running car in a Costco parking lot on Route 110 was taken on a frightening ride Friday by a would-be car thief.

The toddler, who was not identified, was waiting in her car seat while her mother returned an empty cart to a collection area just steps away from the car. Police say the carjacker spotted the running vehicle, jumped inside, locked the doors and attempted to speed away. The child?s mother was knocked to the ground after trying to stop him by grabbing the car?s door handle.

The baby and car were later found about a half mile from the scene. Police are still looking for the suspect.
