Re: I suppose it's a bit late to suggest...
Seriously...
My heart bleeds for the parents and teachers who actually want to parent and teach in the UK/US. Since the nanny-state and cotton-gloved numptys continue to expand I think I might begin offering Caribbean Attitudinal Neurological Integrated Nice-child Generating camps.
I think, calling in the police was a great idea. By the sounds of it; this little bugger probably only ever feared the cops (cause his parents could never tell him "no" for fear of him divorcing them; and so let him watch "Cops/Thin blue line/etc"). The Teachers & Parents have no effective means of control any more.
I don't beat my kids, but they're sure I will if they step out of line... so they don't. They have also been told that their Teachers have my authority to punish them any way they see fit; and if all that doesn't work, they know they're going to the local prison for the weekend.
This little &*(%^(* doesn't have that.
