http://www.ft.com/cms/s/...bdc0.html#ixzz1bvG6e3TC Statisticians confirmed that overall, just over a quarter of those arrested were aged 10-17 and 46 per cent were between 18 and 24. A third of 10 to 17 year-olds involved in the riots had been excluded from school the previous year, compared with an average of 6 per cent among year 11 pupils – those at GCSE level. The data also showed that two-thirds of young rioters had special educational needs, compared with an average of one-fifth of all pupils in state secondary schools.
