Toronto Police have charged the former principal and two vice-principals at C.W. Jefferys Collegiate with failing to report an alleged sexual assault on a female student, sources have told CBC News.

The school officials, who are on home leave, are facing charges under the Ontario Child and Family Services Act for failing to report the alleged assault.

Police have already charged six males with gang sexual assault, forcible confinement and conspiracy to commit an indictable offence in connection with the incident in which a female student was allegedly sexually assaulted in October 2006.

School officials are required to report this kind of incident to police or the Children's Aid Society.

Information concerning the alleged sexual assault surfaced during the course of an internal investigation following the shooting death of 15-year-old Jordan Manners.

Manners was killed last May in a hallway at C.W. Jefferys.

A subsequent investigation headed by lawyer Julian Falconer unearthed the information concerning the alleged assault and passed it along to the Toronto District School Board. 

The board contacted police who have now laid charges.

If convicted, former principal Charis Newton-Thompson and vice-principals Silvio Tallevi and Stan Gordon could face fines of up to $1,000.
