ATLANTA | An Atlanta police officer has shot and killed a man accused of stealing an unmarked police vehicle at a gas station.

Georgia Bureau of Investigation spokeswoman Nelly Miles tells news outlets a plainclothes officer was pumping gas in southwest Atlanta on Tuesday night when a man jumped into the driver's seat of the city-issued car. Miles said in an email Wednesday that the officer is assigned to the department's executive protection unit, which guards Atlanta's mayor.

The officer confronted the man, and fired shots at him. The suspect drove off, but crashed into two vehicles. He was found dead in the car.

The GBI says there was no indication the suspect was armed. The officer was not shot.

No identities have been released.
