The parents of a former Sage International School of Boise student have sued the charter school, alleging officials responded with “deliberate indifference” to an alleged sexual assault.

The Idaho Press reported on the lawsuit Thursday.

In the lawsuit, the parents say school officials failed to properly investigate the alleged off-campus attack. This, in turn, created a hostile on-campus environment.

According to the lawsuit, a male Sage student forcibly held down and groped a female classmate in his home on Jan. 2. In the lawsuit, the parents say their daughter eventually withdrew from Sage, the Press reported, in order to avoid contact with her alleged attacker.

In a statement to the Idaho Press, Sage said it “denies any wrongdoing as alleged in the complaint. As a matter of policy, to protect the rights of all parties, we do not comment on any pending litigation, especially where the litigation involves allegations of student misconduct.”

The parents have demanded a jury trial, the Press reported.
