BELLEVUE, Wash. -- Police here have arrested a woman for allegedly raping her daughter's 14-year-old boyfriend.

The 32-year-old woman, who was arrested Thursday at her home for investigation of second-degree child rape, has not been charged.

Police spokeswoman Carla Iafrate said the crime allegedly occurred at the woman's home and was brought to the attention of police last month by state Child Protective Services workers.

Details of the alleged crime and CPS case were not available.

Investigators expect to send the case to the King County Prosecutor's Office later this week, Iafrate said.
