Toronto police say a man they arrested in 2013 in connection with multiple sexual assaults dating back to 1990 may have assaulted other victims.

The suspect is already facing 15 charges in connection with assaults against five victims which allegedly occurred between 1990 and 2010. In each case, police said the victims, who ranged in age from 5 to 35, were known to the suspect but not through work.

Police said developments in the case led them to believe there are other victims who have not yet come forward. They also suspect he may have also used drugs to carry out an assault on one occasion.

Juan Moran of Toronto faces charges including seven counts of sexual assault, five counts of sexual interference and one count of forcible confinement.

Anyone with information is asked to contact police at 416-808-2300.
