A woman has been charged with hitting a teenage girl in the face with a hammer Monday night in the Gold Coast.

Hannah Walker, 36, was charged with a misdemeanor count of battery causing bodily harm, according to Chicago Police.

Officers responded to reports of a battery about 9:15 p.m. in the first block of East Chicago Avenue, police said. When they arrived, they found a 16-year-old girl with a laceration to her forehead.

Witnesses told police that the girl got into an argument with Walker, who struck her in the face with the hammer, police said. The hammer was found behind a counter and taken into evidence.

The girl was treated for her injuries at the scene, police said.

Walker, who lives in the Hermosa neighborhood on the Northwest Side, was expected to appear in court on Aug. 1.
