A 30-year-old man is facing five charges arising from an investigation into sexual assaults in Toronto and Vaughan, Ont.
York Regional Police say an 18-year-old woman was assaulted at her front door in Vaughan on May 26 after being followed from a bus stop.
They say Toronto police investigators were working on three similar cases that occurred on March 24, June 8, and June 21.
Police say tips received from the public helped identify a suspect and a Toronto man was arrested on July 7 after being detained by Canadian Border Services Agency at the Ambassador Bridge border crossing in Windsor, Ont.
Le Roi Saul is charged with four counts of sexual assault and one of criminal harassment.
Investigators believe that there may be more alleged victims and are appealing to anyone with information to contact them.
