Calgary police are looking for help from the public as they investigate an assault on Halloween night that left the victim severely injured. Police were called to the parking lot of a strip mall at 4774 Westwinds Dr. N.E. just before midnight on Oct. 31 for reports of an assault. Officers spoke with several witnesses at the scene, but say the victim left before they arrived. An hour later, a man — who police determined was the assault victim — was brought to hospital with serious injuries. Police say the victim remains in hospital in critical condition. Investigators are asking anyone who was in the area at the time of the assault, or who may have information that could help advance the investigation, to come forward by calling 403-266-1234. Tips can also be submitted anonymously through Crime Stoppers. “Any piece of information, no matter how small, may positively impact the investigation,” police said in a Tuesday news release.
