I have read numerous discussions where people mention that schools cannot legally prevent a child from leaving, yet I find myself in this exact situation. The school is refusing to allow my child to leave, despite my clear instructions. I've sent an email, filed a complaint with the trust, and even contacted the police, but to my surprise, none of these actions have resolved the issue. I was told by the head teacher that the law does not apply to them. Any ideas on who to contact?
