Home Office analysis shows a total of 1,782 children aged 10 to 17 went to court for robbery offences during 2000. But 1,077 cases were withdrawn, dismissed or ended in not guilty verdicts - cases collapse because witnesses fail to turn up, evidence is weak or courts lose patience with Crown Prosecution Service delays. Of the 705 convictions, most led to community sentences, which can include orders to repair damage or pay compensation. A total of 258 ended in immediate custody. The length of each sentence is unclear, but national Prison Service figures show that most convicted young robbers get tough jail terms - 44 per cent are sentenced to between three and 10 years, a further 36 per cent get 18 months to three years, 11 per cent between one year and 18 months, and the remaining 10 per cent get sentences of less than a year.
