RCMP say they’re struggling to contain the spread of shocking photos posted on Facebook showing a drugged teenage girl being gang raped at a Maple Ridge rave.

Insp. Derren Lench said anyone caught distributing or possessing pictures or videos of the attack could be charged with child porn offences.

“Every time it’s shut down on one Facebook (account), it seems to reappear and it’s been shared in several communities in the Lower Mainland, so the victim has to relive it on a daily basis,” Lench said.

“(The photographs are) just one portion of a larger investigation.

“Obviously the sex assault aspect is our primary focus.”

The assault happened sometime late Friday night or early Saturday morning. As many as seven teens and men are suspected of having taken part while in a field outside a private party.
