The eight year-old girl was taken to the Fort St. John Hospital where she was assessed and released with non-life threatening injuries.
The male was charged with Assault Causing Bodily Harm, and remains in police custody. He cannot be named as he is a youth.
Fort St. John RCMP say that at this time they are looking into any link between this assault and the two recent incidents of a male approaching a female at Rotary Park. Members of the Serious Crime Unit are assisting with the investigation.
