Two more arrests have been made in an alleged gang rape that made headlines last year after photos of the incident were widely shared on Facebook.

The arrests come as the 16-year-old girl at the centre of the case says that intense bullying has forced her to leave classes.

RCMP Sgt. Peter Thiessen read a statement from the girl on Thursday afternoon that thanked her supporters during the ordeal.

"To the people who did not support me, who called me names, who spread lies about me, thank you because you made me much stronger than I've ever been before," she said in the statement.

Two teen males, 18-year-old Colton Ashton McMorris and 19-year-old Allen Warrington, now face charges of distribution and production of child pornography.

Last fall, a 16-year-old male was also charged in the case. Thiessen said it's unlikely that any more charges will come from the case.

In a separate statement, the girl's family wrote about the ongoing struggles their daughter has faced following the Sept. 10 incident.

"Our daughter has been bullied and therefore has had to leave school. Hopefully these charges will help to prevent any more attacks on her character."

Police have always maintained that multiple suspects took part in the incident, which was photographed with cell phone cameras and uploaded onto Facebook.

"The information that we received from witnesses, statements that we received clearly indicated in our minds that that was the case. However, bringing that before the courts is a whole other issue and obtaining the appropriate evidence to support those charges," Thiessen said.

"At this point, we don't have the evidence to support the allegations and the statements and the information we have in regards to further charges."

In the days following the case, police sorted through lurid reports that the girl had been drugged.

However, police said Thursday that toxicology tests showed no sign of drugs or alcohol. Still, Thiessen noted that the tests were carried out more than 20 hours after the incident.

Police added that many teens would not speak openly about the case, and that many investigating officers faced a "code of silence" when questioning potential witnesses.

"There are individuals out there that we feel played a significant role in this. They know who they are. We have spoken to those individuals. They do have an opportunity to clear themselves if they choose to. They have not chosen to," Thiessen said.
