All charges against six male youths accused of sexually assaulting a Muslim girl at C.W. Jefferys Collegiate Institute have been dropped.

The teens were alleged to have forced the student to perform oral sex on two of the boys in the school's bathroom in the fall of 2006.

Toronto police charged the boys last September with gang sexual assault, forcible confinement and conspiracy to commit an indictable offence.

However, the charges were dropped on Wednesday.

"Following a thorough review of the evidence in the case, and after speaking with the complainant and her family, it was determined that it was no longer in the public interest to proceed with a prosecution," Brendan Crawley, a spokesperson with the Attorney General's office, wrote to in an email.

Without discussing specifics of the investigation, Crawley said such decisions are made "based on the unique set of circumstances of the individual case."

Crawley added the teens, who cannot be identified under the Youth Criminal Justice Act, have agreed to enter into peace bonds for a period of one year.

In December 2007, police charged the school's former principal and two former vice-principals under the Ontario Child and Family Services Act for failing to report the alleged incident.

Earlier this year, those charges were dropped. A justice of the peace decided too much time had passed between the alleged assault and the charges, which were laid in January after separate reports of the incident were given to a panel reviewing safety in Toronto schools.

An investigation at the school began after 15-year-old student Jordan Manners was shot and killed at the North York school in May 2007.
