My classroom had this weird hidden "library" at the back of it and various teachers would randomly take students to the back of it under the pretext of performing "health checks" that really were them just taking us there and raping us. Mostly a few specific male teachers including the principal and my female teacher as well. One time I was selected to undergo a health check and refused and the teacher slapped me so hard across the face I fell out of my chair and hit the ground. This was in like second grade too so we were pretty young.
That school has been shut down and the buildings leveled now. No idea if anyone was ever persecuted over it though.
