Brother Jean-Paul Thibault, 72, is accused of using his position of authority to commit sexual assault and indecent exposure at the college in Mont-St-Hilaire.
Police say the crimes took place between 1982 and 1989, partly at the college where the adolescent victim was boarding.
Thibault, a Lac-Sergent resident, is still part of college’s board of directors. He also belonged to the congregation of Frères de Notre-Dame de la Miséricorde.
Following their investigation, Richelieu-St-Laurent police, who were assisted by the Sureté de Québec, believe there may be other victims of Thibault.
Police captain François Cinq-Mars has asked that other victims contact the Richelieu-St-Laurent police department.
