Police are searching for a young man they say grabbed a woman from behind Friday afternoon and tried to drag her into the woods near Lac Leamy Park.

The suspect, described as between the age of 15 and 18, allegedly attacked the 31-year-old woman at about 1 p.m. as she walked along a bike path near the park.

She fought back and got loose from the suspect's grip when a passer-by came to her aid. The suspect fled on a black 10-speed bike.

He was described as wearing blue shorts but no shirt, police said.

Police conducted a sweep of the area but could not find the suspect.
