I was initially confused myself as to which school in Bradford had seen a teacher stabbed by a pupil. This is because it was described as "Dixons King's Academy" and the Dixons group sponsored one of the very first academies, in Bradford many years ago.
However, it has become clear that the school was formerly the infamous "free" school, King's Science Academy. It was apparently taken over some months ago by what is now the Dixons academy chain. It's not clear to me whether it is still a "free" school or a slightly more conventional "academy". Either way, of course, we are all still paying for it.
