Days before the anniversary of the disorder, official figures show that 44 per cent of riot suspects have been arrested on suspicion of committing fresh offences within the last 12 months.
The statistics, released under the Freedom of Information Act, have raised serious questions over the penalties handed out to offenders.
More than half of those locked up over the riots are already free and thousands more have evaded justice. Police in Nottingham made 143 arrests following the disorder in August last year. Of these, 86 were charged.
But in the last 12 months, 72 suspects – half of those arrested – have been held again for crimes including rape, arson, robbery, threats to kill and breaching bail or parole conditions.
