TAMPA, Fla. -- Tampa police said three teenagers tried to steal an undercover police car with the officers still inside.

The police report said the officers saw the teens looking into parked cars late Monday night. The officers followed them in their unmarked police vehicle, pulled into a parking lot, then waited.

Police said the teens walked toward the car with screwdrivers, a flashlight and a piece of concrete in their hand.

The officers then got out of the car and chased the teens. Two were arrested. The third got away.

Police said the teens admitted they were going to steal the car and that they didn't know it was a police vehicle.

The teens, ages 15 and 17, were charged with auto burglary, possession of burglary tools and resisting arrest without violence.
