Never leave your car running with the doors unlocked.

That’s the lesson one driver learned Tuesday in Boca Raton, Florida. John House left his 12-year-old daughter, Sierra, inside his unlocked 2003 black Nissan Murano and went inside a gas station.

In that short time span police say 14-year-old Tottiana Canteen ordered Sierra out of the car and sped off. Responding officers eventually caught up with the car and placed stop sticks to disable the vehicle. They say Canteen turned into a parking lot to avoid the barriers and a police cruiser got in behind her. Police say as the officer got out of his car Canteen backed up and smashed into the cruiser.

That’s when she was arrested.

Canteen later told police she and a friend walked to the gas station where they sat on a bench for about three hours.

She said her friend told her to take the car.

After forcing the 12-year-old out of the car she picked up her friend and later dropped her off near JC Mitchell School. Canteen said she planned to drive to Delray Beach to visit a friend.

Canteen faces charges of carjacking, possession of marijuana, driving without a license and improper backing. Police are also investigating whether Canteen was involved in stealing a car from the same gas station the day before.

No one was hurt during the incident.
