Montreal police are hoping to find other potential victims following this month's arrest of a 40-year old man linked to a sexual assault.
Oba Femi Toussaint, who remains in police custody, has appeared in court.
He faces charges, including aggravated sexual assault, sexual contact, confinement, drugging, and breach of conditions.
Police say the suspect forced a 15-year-old girl to follow him into an underground garage in the Ville Marie borough.
They add he forced her to take drugs, and then sexually assaulted her.
Other potential victims or witneses are urged to file a report at their local police station or call 911.
