WEST TOWN — A bicyclist who admonished a woman driving a white Audi convertible for ignoring a stop sign was chased down by the driver, yanked off her bike by the hair and then punched in the face this week.

The Audi driver, who escaped arrest by driving off, also threw a wrench at the bicyclist in the West Town road rage incident, according to police and the bicyclist, who asked not to be named.

The end of the incident was captured on a home surveillance camera. It shows the bicyclist being jerked backward as another woman pulls her long blonde hair. After the bicyclist is off her bike, the attacker, while still pulling the woman’s hair, throws a right hook into the victim’s face.

It happened around 1:35 p.m. Tuesday in the 1300 block of Hubbard Street.

The 53-year-old woman was riding her bike when she got into “a verbal altercation” with a driver who was between 20 and 30 years old, said Officer Jessica Rocco, a Chicago Police spokeswoman.

The bicyclist, who posted about the incident on Facebook, said she was riding down Hubbard Street, near Ogden, when the woman driving a white Audi convertible “blew through a stop sign” in front of her.

“I said ‘nice stop’ to her as I biked past so then she tried to hit me with her car screaming ‘MIND YOUR OWN BUSINESS!’ chased me down Hubbard, across Ogden, threw a tire wrench at me and jumped me,” the cyclist wrote in a Facebook post.

A pedestrian who witnessed the incident called 911.

The cyclist told Block Club that the driver ran up behind her and yanked her off her bike by the hair.

The driver of the car got back into the Audi and drove off. The cyclist said the car’s license plate started with “J1.”

No injuries were reported and no one is in custody, according to Rocco, who said officers “toured the area for the offender with negative results.”

Area Central Detectives are investigating, Rocco said.
