Chicago police have taken a woman into custody they say attacked at least nine other women with a metal bat in six different incident this week.

The attacks took place on Sunday and Tuesday, police said, in neighboring communities on the city’s northwest side, WMAQ reported.

Witness reports say the woman, who has not been identified, stops her car in the middle of the street, gets out, and attacks.

“At first, I thought it was a joke, then when she started hitting them it wasn’t a joke,” said witness Shannon Condon, who lives in the Ravenswood Manor neighborhood and captured one of the attacks on video

“A white car pulled up and a woman got out of the car with a baseball bat and basically started attacking two women with the stroller,” she said. “Either the mom or aunt said ‘I have a baby! Back off,’ and she didn’t back off.”

Six of the attacks took place on Tuesday, police said. They said many of the victims declined medical attention, although at least one took herself to a nearby hospital. She is in good condition, investigators said.

No charges have been filed, police said.
