ST. PAUL, Minn. (AP) — St. Paul police are investigating how a running car was stolen with a 6-year-old boy in the back seat.

Sergeant Paul Paulos tells the St. Paul Pioneer Press the boy's bother was hysterical when she called 911 on Thursday afternoon. Moments later, the thief dropped the child off nearby unharmed, then sped off again in the stolen vehicle. Police later recovered the car.

Paulos says the 27-year-old mother had parked outside a beauty supply company and left her son in the back seat with the engine running. She returned to find the car gone and called 911, but a few minutes spotted her car as her son was getting out. She didn't get a look at the thief.
