The 17-year-old girl became separated from her friends, was approached by a male she didn't know and was taken into a wooded area where she was sexually assaulted on Tuesday night, said RCMP Cpl. Cheryl Bush.
RCMP had deployed extra resources to conduct road blocks leading into the bush party and liquor and drugs were seized before the grads went into the event.
"It was crazy. I mean there had to be upwards of 1,000 people there. It was like some sort of dance club," said Kamloops Grade 12 student Gage Chamberlain, who attended the party in the Tree Flats area.
Police want anyone with photos or video of a sexual assault at a bush party to contact the Kamloops RCMP.
"At the time, somebody may have recorded this incident, maybe unaware that it was a sexual act taking place versus something that they thought was ok to videotape," said Bush.
“We feel the community can play an important role in assisting our investigation in providing support to the victim rather than victimizing her further," she added.
Bush warns that anyone caught distributing video or photos of this nature through social media could face criminal charges.
Earlier this year, a man was sentenced for distribution of obscene material after he posted photos of an alleged rape of at teenaged girl at a Pitt Meadows rave.
