Police say a 25-year-old Korean exchange student, who posted an ad in Toronto looking for help learning English, was allegedly sexually assaulted by a man who responded to the ad.

Authorities say the student posted the ad and a man named Karl Kim responded. They met at a restaurant on Monday.

Police say a couple hours later, the suspect brought the student with him to a friend’s house, where she was sexually assaulted.

Michael Chiong, 31, of Mississauga, also known as Karl Kim, is charged with sexual assault, forcible confinement, possession of property obtained by a crime, theft and failure to comply with recognizance.
