Calgary police say a man in his 20s is facing charges in connection with a random sexual assault that took place in a CTrain station over the summer. Police were called to the Southland CTrain station in the early morning hours of Aug. 25 after witnesses had reported a vulnerable woman in distress who appeared to have been sexually assaulted. She was taken to hospital in stable condition. Investigators did not believe the woman knew the assailant before the attack. On Friday, police said in a news release they charged 25-year-old Sedat Kaya with one count of sexual assault in connection with the incident. He is expected to appear in court next month.
