Calgary police are investigating a sexual assault that happened on a pathway in the community of Canyon Meadows.

Police believe the attacker followed her Sunday night and sexually assaulted her on a pathway in a green space between Canata Close and Canterbury Drive S.W.

"It is a stranger attack. She did not know who this person was," said Insp. Monty Sparrow. "It causes us great concern. It happens very rarely in the City of Calgary that we have this type of sexual assault."

Followed victim

Police have released security camera footage of a person who may have information about the attack.

The woman, in her 20s, boarded the C-Train in the northwest. At Chinook Station a man got on. They both exited at the Heritage Station and boarded a Calgary Transit bus at 10:55 p.m.

Police say they were the only passengers and both got off the bus at Elbow Drive and Canata Place, S.W. about 15 minutes later.

“The man followed the woman as she walked westbound. As the woman walked on the pathway through a green space between Canata Close and Canterbury Drive S.W., it is alleged the man ran quickly towards her.”

Police allege he threatened her with a weapon and repeatedly sexually assaulted her.

“The victim was eventually able to run to safety, where she called police. She was then transported to a local hospital to be treated for minor injuries.”

Sparrow said they are also trying to locate a man who was sitting on the stairs of the Heritage Station who they believe talked with the suspect. Police don't believe the men knew each other.

Anyone with information is asked to call police at 403-266-1234 or to contact Crime Stoppers.
