Police arrested a woman who attacked another woman’s car Sunday, police said.

Nancy Wharton approached the car at the 2000 block of Darrow Avenue on Sunday around 11:50 p.m., Evanston Police Cmdr. Tom Guenther said. Wharton began pounding on the window with her fists while the owner was inside the car, Guenther said.

The victim locked her door, and the suspect threw a rock at the driver’s side mirror before walking away. Police arrived at the scene and found Wharton, whom the victim identified as the woman who threw the rock at her car.
