KINGSTON, Tenn. -- The family of a 16-year-old Tennessee high school student has filed a lawsuit against Roane County Schools and the contractor who employed a female janitor accused of raping the boy during school hours.

Citing the lawsuit filed Monday, the Knoxville News-Sentinel reports that the Midway High School student's family is seeking $4.5 million in damages from the school district and Compass One Services of Tennessee for negligence in allowing the rape to occur.

Twenty-nine-year-old Jessica E. Galyon was arrested in February on multiple charges related to the assault. Authorities said at the time that high school officials received reports in October 2016 of Galyon exchanging sexual Facebook messages with a student, CBS affiliate WBTW reported.
