According to investigators, the 21-year-old woman was arriving at her home in the 2100 block of Locust Street near Rittenhouse Square after going to a pizza shop. It was pouring down rain.
As she arrived home, a man approached her and sexually assaulted her at knifepoint.
"He came up from behind me and grabbed me up my skirt. Then I turned around and hit him and yelled at him. Then he said he had a knife," the victim told Action News.
"I maced him and then he started punching me. He pushed me down. I started yelling for help and maced him again," she said.
"I was really frightened. They said I did everything I should have done. I wasn't going to let him in my apartment at all. That was never an option. I'm just glad I'm okay."
The suspect is described as a black man in his late 20s to early 30s. He's about 5'10" tall with a slim build and a dark complexion, short hair and a goatee. He was wearing a black t-shirt, a navy blue jacket, and a red Phillies hat.
Police are warning women in the area to be on the lookout. An intense manhunt is underway.
