Thanks for posting this as I hadn't seen it. Very worrying.
I have a son in RGS year 7 and they haven't' been given ipads, well he hasn't come home with one!
Ds1 thought they had, he is so huge now that yr8 kids look like yr7! (Never believe teenagers)
At the end of the day there are still lots of fairly young kids wandering around high wycombe after school with 3-400 pounds worth of tablet plus often phones, in their bags, it was sadly inevitable that sooner or later a child would be mugged.
V worrying though, even more worrying is that my boys thought someone should have stopped the thief as the high st must have been busy....long lecture on personal safety v "stuff" and the importance of just letting go if someone bigger, stronger, desperate and possibly armed with a knife wants your bag.
