Forest Hill School have done as much as they can, I think, with regard to this recent spate of muggings. Ironically, mobile phones are banned in the school and most of the pupils don't even take their phones to school with them. I feel so sorry for your son, OP, and all the other young folk who have been targeted like this. Where do all the phones go? I just can't believe that there is a huge black market for them!
