Sexual assault at school?

Question

So a bit of background story, (sorry if it's long, just need advice)

I became friends with this guy last year from high school, we'll call him Jay. We're both currently 17.  So Jay and me were friends, I THOUGHT we were. I've figured he's a bit twisted, the first weird incident was he dated my friend to become close to me then broke up with her when we became close friends. He admitted he liked me, and he wanted to make me jealous.

The main reason I'm writing about this is that all of this year he has been sexually assaulting me during school. This incident happened today

I have had a sore back for some time lately and Jay started giving my back a massage, it was uncomfortable but I didn't want to cause a scene. He started going down my back and told me to "arch it" and then he slapped my ass, Then next thing I know he's choking me with his arms and I said STOP because I couldn't breathe and he stopped. Then he starts hugging me from behind, tries to kiss my neck and my cheek and this whole time i'm pushing him away and telling him to stop. We then had to move into a smaller room and he does the same thing, massage and then he starts at my collarbone and then touched my breasts and i pushed him and said stop. I tried to leave the room and he dragged me back and pushed me against the wall. I sat down and then he tried putting his hand on my thigh and up my dress but I left. 

I want to tell a teacher. What should I say? can i remain anon or will he know it was me?

Answer 1

Tell your parents what has been happening and also tell your teacher immediately. This guy will be expelled from school. You should have said something when it first occurred, but it will continue unless you stop it because he thinks that you like it because you've been letting him touch you and abuse you by not speaking up.

Answer 2

police as the other said. Stranglings /choking is a seriously bad sign. Youll have a hard time proving sexual assault and physical assualt but report it and get an order placed on him by the courts.

Answer 3

Don't bother with a teacher, go straight to the police now.
