A Sherbrooke, Que., man is facing charges after allegedly sexually assaulting a 10-year-old child in Ottawa earlier this year.

Ottawa police say they got a tip on Monday that an adult man had sexually assaulted a child in Ottawa earlier this year.

On Friday they announced that a 28-year-old man from Sherbrooke had been charged with one count of sexual assault, one count of sexual interference and one count of invitation to sexual touching.

He is expected to appear in court in Ottawa on Saturday.

Police say he's been known to visit the Ottawa-Gatineau, Embrun, Ont., and London, Ont., areas over the past few years, and investigators are concerned there could be other victims.

No other information about the child is being released.

Anyone with information is asked to contact the Ottawa police sexual assault and child abuse unit at 613-236-1222, ext. 5944.
