Less at the school, more to do with a handful of female students. A would-be rapist im a balaclava would lurk in the woods between the train station and the town, late in the evening. A few times he'd leap out, grab a lone student, but before he'd do anything would let out a slightly disappointed moan as he jizzed in his own pants from the excitement, then would let them go, and trot despondently back into the woods.
A few girls reported this. All said it was a horrible, terrifying experience, but anyone they told would usually laugh with relief.
