A 46-year-old woman ended up in Chilliwack General Hospital after being assaulted while she was out for a run along Hope River Road on Fairfield Island, at approximately 11 p.m. PT on June 6.
The woman told police a man she didn't know, wearing dark-coloured pants and a dark-coloured long-sleeved shirt, attacked her near Williams Road, close to the front entrance of Gwynne Vaughan Park.
The woman fought back and the man ran south towards the river. Investigators believe he intended to sexually assault her.
Chilliwack RCMP Const. Tracy Wolbeck said police hope someone will recognize the man in a sketch provided by police.
"In these types of investigations, the police rely on the public's help," she said.
"This incident is very concerning to the police and we are hoping that the community can assist us with identifying the man in the composite sketch to further our investigation."
Police described the suspect as a white man in his 30s with longer hair pushed to one side and facial hair with one or two weeks of growth. He has a slim-to-medium build and a mole or mark on the left side of his face.
Const. Wolbeck said that the sketch police provided is an artistic interpretation that was made based on witness statements.
"In this case there may be certain characteristics that may not exactly be the true likeness of the suspect involved in this case, but may be similar in nature," she said.
