The Macomb County Sheriff's Office says the 14-year-old told police she tried to pass three older males on the trail, but one of them yelled at her then came towards her.
The teen says he grabbed her by her sweatshirt, and when she tried to pull away he slapped her across the face, causing her to fall down.
She says he then pulled out what appeared to be a knife, and used it to cut off her pony tail. She says she was dragged and dropped in a puddle before the men ran off.
A neighbor who called 911 says the girl "was crying, all balled up on the floor at my front door saying three men attacked her."
According to the woman who called 911, the teen was jogging when she was attacked.
The suspect is described as a white male being 16 to 18 years old. He is approximately 5 feet 6 inches tall with a dark-stubbled beard and moustache. He was wearing a red hooded sweatshirt with white lettering.
The sheriff's office says the other two males did not take part in the alleged assault. They are described as being older, possibly 20. They were wearing black sweatshirts.
The teen got a small cut on her lip that did not require medical attention.
Residents in the area that live along the path say this incident is frightening and they can't believe something like it would happen so close to home. Jason White says it is very scary, "the walking path is right behind our house and of course, the school is right next door."
The sheriff's office asks that anyone who has information about the assault to call (586) 307-9358.
