Thistlelass the headteacher and head of year were not necessarily the ones who were responsible for safeguarding in Arthur’s school. It has been reported that his class teacher reported concerns about Arthur. The teacher would have reported the concerns to the teacher in charge of safeguarding in his school. Every school has one person who is the named person in charge of safeguarding. This person may, or may not, be the headteacher, the deputy headteacher, or another teacher, but that person is then responsible for contacting Social Services about the child causing concern.
Schools were closed when Arthur was being abused. He didn’t return to school when they began to operate, and subsequently died on 16th June 2020. I have long said that schools should not be closed. That his school was closed almost certainly was a large factor in Arthur’s bullying, torture, and eventual death. Schools are safe places, often the safest place, for children who are being abused.
