A man struck a 48-year-old woman in the head and knocked her onto the L tracks after she asked him to stop urinating on the Belmont Red Line platform Friday evening, police said. CWBChicago spoke with the victim on Saturday evening. No one is in custody.

Police said the victim’s head struck a train rail and the woman broke her arm by trying to cushion her fall.

The victim said she was on the northbound platform a little after 4 p.m. Friday when she saw a man urinating nearby. “I walked by him and said, ‘You can’t do that in a bathroom?’”

“He told me to f*ck off. I took a picture of him and he said, ‘I’m going to kill you, b*tch.’ I flipped him off and started walking away.”

That’s when the Rogers Park woman felt a hit to the back of her head.

“I fell off the platform and landed headfirst on the tracks,” she said. “A bunch of people ran to the edge of the platform, motioning me to go over there so they could pull me up. I was really shaky and couldn’t get up on my own. A couple guys jumped down, helped me up and walked me to the platform.”

By the time police arrived, the suspect was gone. “I’d never seen him before,” the woman said. But she still had that picture. We’re sharing it here.

Taken to nearby Advocate Illinois Masonic Medical Center, the woman had eight staples placed in her head and a soft cast put on her hand and forearm, she said. Saturday night she told us, “I’m hopped up on Tylenol with codeine. When that wears off, the pain can get a little intense.”

We’re withholding the victim’s name at her request.

Police on Saturday evening confirmed details of the woman’s report and said that Area North detectives are investigating the case.

The suspect is described as black, 30- to 40-years old, about 5’10” tall, and 180 pounds. He was wearing a black jacket with an olive green Cubs hat and he carried a large backpack.
