Peel police are appealing for witnesses after a sexual assault Wednesday morning near a Brampton lake.

Around 9:45 a.m., a 20-year-old Brampton woman was jogging around Professor’s Lake and tripped, falling on the ground of an unpaved trail. A man then dragged her to a nearby wooded area, police said in a news release Thursday, June 13.

The man grabbed the woman by her waist, picked her up and pushed her against a tree, police said.

Investigators said the woman struggled with the man, kicking him in the leg, but he wouldn't let go. The attack was interrupted by a witness walking by. The attacker then fled toward a recreational centre.
