Police are looking for information on a racist road-rage attack that reportedly occurred in December in Cottonwood Heights.

The assault began when a man driving a Nissan Altima flagged down a man driving a Volkswagen Jetta on Dec. 19, near a Famous Dave’s restaurant at 1200 East and Fort Union Boulevard, Cottonwood Heights police wrote Monday.

The man in the Jetta pulled into the restaurant parking lot and got out of the car to learn why the other driver had flagged him down, police wrote. The driver of the Altima also got out of his car and opened its back door, releasing a dog and commanding the dog to attack the other driver, police wrote.

The driver of the Jetta hit the dog — which appeared to be a German shepherd — to protect himself, police wrote; the other man then held the Jetta driver down while the Altima driver’s girlfriend and the dog attacked him. The Altima driver was yelling profanities and racial slurs at the driver of the Jetta, police wrote.

Police described the attack as an act of road rage.

The driver of the Altima was described as white, about 30 years old, 6 feet 2 inches tall, 180 pounds, with curly, blond hair. The female passenger was described as white, possibly having black hair with blond highlights.

The Nissan Altima was black, police wrote.

Anyone with information on the attack may call police at 801-944-7100.
