A Utah man is in jail after he refused to return a car he was test driving — while the salesman was still inside.

The 43-year-old Centerville man was booked into the Salt Lake County jail for investigation of kidnapping, pending formal charges.

According to a probable cause statement, the man went to a Salt Lake City dealership on Saturday and took a car on a test drive, stopping at “different locations” along the way. When the salesman told the suspect to return to the dealership, the man refused.

The salesman told police that when he called 911, the man began “driving 100 mph on the freeway … turned the music up and rolled all the windows down … so the dispatcher could not hear him provide his address.”

After the car was stopped by the Utah Highway Patrol, the man said he was “scared of the sales associate because he kept yelling at him and grabbing the steering wheel trying to have him pull the vehicle over” so he was “scared to stop the car and kept driving.”

The man is being held without bail.
