My DS who is 11 and in year 6, had a child threaten him on a class chat. A child posted a video and he said he didn't like this particular character but another, and he literally recieved a hate campaign from 2 individuals which ended with one sending a threatening message of violence. This wasn't threatening to punch them, but more in the context that would require hospitalisation and potentially surgery. The details may mean this isn't confidential hence me not expanding. I reported to the school as DS was worried about going. I kept screen shots of the messages but the school refused to view these as they stated they couldn't. Their solution was to interview everyone on the group chat to no real conclusion (surprisingly, no one admitted to seeing the threat but I can prove 2 children reacted to it). So they then proceeded to sit DS (who is SEN) in the same room as the the one who threatened him to understand and resolve the issue. My DS said they told him no one saw anything on the chat and asked him if it happened to which he affirmed it did. He then said teachers told him they were bringing the perpetrators in to discuss and he said "ok" as he didn't feel he could say no. I naturally wanted to discuss this with the school to understand their reasoning and they have said DS asked for and prefered them to be in the same room. He wet himself telling me about this happening, so I feel there was certainly some distress there. However, the school proceeded to laugh in my face saying I didn't know how DS felt, and that sitting them down together was a procedure they felt necessary. They also said they didn't have to support as it was off school grounds and implied I should be grateful for some intervention from them.
I just would like to understand if this is actually normal procedure or if anyone has experienced this. It wasn't dealt with under the bullying policy as I was told its not repeated enough to be dealt with under that policy. There have been incidents in school also which they are aware about, so this is not isolated. I have a younger child at the school also.
Any help and advice on this appreciated from personal experience and those with expertise in this area. Thank you in advance.
