RCMP in Kamloops are investigating allegations that a teenaged girl was sexually assaulted at a grad bush party overnight in the Tree Flats area of Barnhartvale. RCMP had extra resources on the road leading to the party to check for liquor and drugs - and seized a quantity of booze and made one drug bust. Police estimate up to 1000 youths were in the area from various high schools. This morning (Wed) they received a report that a 17 year old girl left the party and told her parents she had been assaulted. They took her to hospital and notified police. She says she become separated from her friends, and was approached by a male she did not know. She says the male eventually took her into the bush area and sexually assaulted her. She used her cell phone to get picked up from the party. RCMP say it's possible the incident may have been photographed or filmed. Cnst. Cheryl Bush says "As this event strongly resembles recent cases that have been largely publicized, RCMP investigators believe there are individuals who witnessed what took place and have photographs of the incident. We want to see this case unfold differently for this victim, compared to what has happened in the past". Bush says such photographs would be evidence to a criminal act, which must be turned over to authorities, rather than be posted or distributed. Police will investigate any instances of these photographs being mishandled, which could result in charges of making, possessing or distributing pornography. Such offences could carry maximum sentences of up to ten years imprisonment. Anyone with information regarding this incident is asked to contact Kamloops Rural RCMP at (250)314-1800 or call Crime Stoppers.
