Police in Canada on Monday announced the arrest of a Toronto-area karate instructor on charges of sexual assault against an underage former student. The York Regional Police said they arrested Ray Tio, 47, last week following an investigation into allegations made by the female student who said she was assaulted by Tio in 2016 when she was 13-years-old.

The website for Tio's World Class Karate school lists him as a sixth dan in shotokan with the Japan Karate Association with numerous medals in national and international competitions.
