Fewer ballots - but bad behaviour grows
Cases in 2002 included an assault on a pregnant teacher and the two teenagers excluded from Glyn technology college, Surrey, for making death threats against PE teacher Steve Tavener. Former education secretary Estelle Morris attempted to intervene, saying the boys should not have been reinstated.
Mr O'Kane said: "Some of the cases have been quite serious, probably more so than in the past. These are youngsters who are virtually out of control."
