Me (30m) single parent, had to console my 10 year old daughter, after she was repeatedly sexually molested by a younger kid, and her teachers did NOTHING

Ok so I need parent advice, but since that is nonexistent, I will ask the Reddit community. Today in after school care, My daughter (10 F 5th grade) I will call her K, was repeatedly groped by a 3rd or 4th grade boy. Apparently, as the teacher has told me, this is an on going issue. She told him no, many times, and he continued. Eventually K had enough and snapped at this kid which lead to an argument. The teacher, trying to break it up asked the younger child to move places, he refused. Again trying to defuse the situation she asked K to move. SHE was PISSED! Argued and eventually complied. The teacher told me K "felt it was incredibly unfair.". I had to bite my tongue, talk down my rightfully upset 10 year old and explain to her the teacher was just trying to stop a fight, though she is the one being repeatedly, sexually harassed. I am livid. We are supposed to be teaching our boys to be better MEN and yet K is the one who is asked to move. "It's ok if he touches you sweetie, just move away" is no longer fucking acceptable! This isn't the 1950s! There is literally a day and a half left in school and I want nothing more than for this little boy to learn the right way to treat a woman, but what really can I do? Go to the Principal? Ignore the situation like society accepts? How do I look my daughter in the eye, as her dad, and tell her there is nothing I can do. Accept the situation, you go to a new school this fall. Advice? via /r/Parenting http://bit.ly/2M1BZtG
