A Mississauga teacher is facing additional charges after two victims came forward with allegations of sexual assault.

Last month, Toronto police alleged a 19-year-old woman was assaulted by a male teacher during school hours over a two-month period, from November 2014 to January 2015. A police statement said was assaulted again between July 6 and July 29.

At the same time, police said 17-year-old girl also came forward to say she'd been assaulted by the same teacher between July 6 and July 30.

As a result of the investigation, 49-year-old Chinedu Okoro was arrested on Aug. 20 and charged with six counts of sexual assault and four counts of sexual exploitation.

Police announced Monday Okoro had been rearrested following further allegations. Officers said a woman told them she'd been assaulted during the month of June. Another woman said she'd been assaulted four times, between April 17 and June 29.

He was charged with an additional five counts of sexual assault.

Police said Okoro was an employee of the Toronto District School Board, working in the northwest area of Toronto. He has since been suspended.

Officers believe there may be more victims, and anyone withy more information is asked to contact them at 416-808-3100 or call Crime Stoppers anonymously at 416-222-8477 (TIPS).
