PETERBOROUGH, Ont. -- Police in Peterborough, Ont., say a 39-year-old man has been charged with sexual assault and sexual exploitation involving a teenager.

Police say they began investigating in March after receiving a report of an alleged "inappropriate relationship" between the man and the teen in 2015.

They say the alleged victim was between 16 and 17 at the time, and the suspect was in a position of trust and authority.

Police say there could be more alleged victims, and they're asking anyone with information to contact them.
