Abbotsford police are looking for witnesses and video as they investigate a sexual assault alleged to have happened early Saturday morning.
Police say it happened around 1:15 a.m. near South Fraser Way and the 2600 block of West Bourquin Crescent.
The woman had flagged down a police vehicle to report the unprovoked assault by a stranger.
She had previously tried to flag down several passing vehicles, police said. The victim was treated in hospital for non-life-threatening injuries and released later Saturday.
The suspect is described as Caucasian, aged 30-35 years old and about five-foot-six inches tall, with short, sandy brown hair, a scruffy, patchy beard and partially rotted teeth.
He was wearing a white T-shirt and black pants and fled on a bicycle.
Anyone with information is asked to contact Abbotsford police.
