My child was threatened by his "friend" today. The "friend" said he would stab him in his eye with a pen. This is not the first incident, he slapped my son across the face two weeks ago, knocking his glasses off. He's previously had to be held back from hurting my child after a disagreement. They are both in year 7, in a mainstream school but in a provisional class for children with autism. They both have asd. They get on for the most part but this "friend" seems to have some anger issues. I'm concerned that he may follow through with his threat considering his past violence/aggression. So here's the next problem, I have called the school asking to speak to someone, they've said that someone would call but nobody has called. Has anyone got any advice on what I can do next? Shall I keep my son off until a safeguarding plan is put in place?
