Police and Pierce County Sheriff's deputies questioned the woman Friday and searched her home north of Tacoma. They seized bedding, credit card receipts and personal belongings, including her Jeep.

Officers were acting on a tip from state Child Protective Services. No charges have been filed, said Dan Donohoe, spokesman for the King County Prosecutor's office.

The woman worked as a teacher's aide at Sacajawea Junior High School until March, when she was transferred to another school in the Federal Way School District, The News Tribune of Tacoma reported.

Due to the age of the alleged victim and the sensitive nature of the case, the Federal Way Department of Public Safety was investigating the allegation.

The Seattle Post-Intelligencer reported that sources said the woman took her student on snowboarding vacations and to hotels and motels for sex.

The paper said the boy was a troubled teenager with a police record who began acting out violently during the six months he was allegedly involved with the woman.
