OTTAWA -- A former priest is facing charges in Ottawa after an investigation into allegations of historical sexual assault.

Ottawa Police say they received a complaint in September and began investigating the allegations of incidents that occurred in the late 1960s.

Police say the allegations involved a priest with the Archdiocese of Ottawa and a boy who was 15 years old at the time.

They say William Barry McGrory, now 82 and living in Toronto, has been charged with two counts of indecent assault and two counts of gross indecency.

Investigators say they're concerned that there could be other victims.
