BELLEVUE, Neb. (AP) — A Bellevue woman has been accused of sexually assaulting her teenage foster son.

The Bellevue Police Department says officers found the 46-year-old woman and the 17-year-old in a parked vehicle Thursday behind a department store. Officers say they suspected inappropriate contact between the two.

The woman was arrested Friday. She faces a charge of second-degree sexual assault of a protected person.

The Associated Press generally doesn’t identify victims of sexual crimes and is not reporting the woman’s name to protect the identity of the 17-year-old.

Police say the teen was placed in the woman’s care through an organization that provides foster services. He has since been placed into protective custody with the state’s Department of Health and Human Services.
