GRAND RAPIDS (AP) - A former officer at a juvenile correctional facility in northern Minnesota has been sentenced to more than eight years in prison for sexually assaulting a 15-year-old resident.

Devin Wood of Grand Rapids was sentenced to eight years and four months in prison Monday on three counts of third-degree criminal sexual conduct. He is also required to register as a sex offender and will be subject to a lifetime conditional release.

The 24-year-old pleaded guilty to the charges in Itasca County court in September.

He assaulted the female resident at the North Homes Juvenile Correction Facility in Grand Rapids in April.
