Saskatoon Police say a 23 year old man and a 17 year old boy are facing sexual assault voyeurism and child pornography charges following an incident earlier this month. On June 8, Police were called to Royal University Hospital where a 15-year-old girl was being treated for injuries not considered life-threatening. It was reported that the girl had been picked up from her home around midnight, and taken to a location along the riverbank where she was encouraged to consume alcohol. She then was allegedly sexually assaulted by two males and left at the location in a vulnerable state. She was discovered some time later by a passerby who called for help. The girl has since recovered from her physical injuries.  Investigators believe there may be other girls or women in the community who have been victimized in a similar way. Anyone with information is asked to contact Saskatoon Police or Crime Stoppers.
