Additional charges have been laid in connection with the gang rape of a teenage girl in an attack that was photographed and posted to the internet.

A 16-year-old girl was raped by several people at a rave in Pitt Meadows, east of Vancouver, in September 2010, police have alleged.

Cellphone photos were taken of the incident and were posted to Facebook.

Colton Ashton McMorris has been charged with sexual assault, while Dennis John Allen Warrington faces a charge of distributing child pornography.

The men made an initial court appearance Tuesday in Port Coquitlam.

More details on the investigation will be released at a news conference Thursday, said RCMP Sgt. Peter Thiessen.

A 16-year-old has already been charged with production and distribution of child pornography related to the incident.
