Update: Suspect charged in transit assault

Investigators have now charged a man in relation to a serious assault that occurred at the Marlborough CTrain Station in July.

On Friday, July 11, 2025, at approximately 4:25 p.m., a man was standing on the platform at the Marlborough CTrain Station, located at 889 36 St. N.E., when he was approached from behind and assaulted. The victim fell to the ground, where he briefly lost consciousness, and the suspect fled the scene. The victim and suspect had no prior interactions and are unknown to each other. The victim was transported to hospital in stable condition, where he was later released.

After further investigation, this assault was determined to have been random.

After a media release in August 2025, we received several tips identifying a potential suspect, who has since been arrested.

Liam James ROONEY, 28, of Calgary, is charged with one count of assault. ROONEY will next appear in court on Wednesday, Oct. 15, 2025.
