http://www.huffingtonpost.co.uk/2011/10/24/rioters-were-overwhelming_n_1027942.html?1319453988Most police forces found that fewer than one in 10 of those arrested over the August riots were gang members and gangs "generally did not play a pivotal role" in the disturbances, figures have shown.
Even in London, where gang membership among those arrested was highest at 19%, most of those held were not in gangs, the Home Office figures reveal.
"In terms of the role gangs played in the disorder, most forces perceived that where gang members were involved, they generally did not play a pivotal role," officials said.
But more than a third of young people aged 10 to 17 who were involved in the riots had been excluded from school during 2009/10, other figures released by the Ministry of Justice showed. This compared with just 6% of all Year 11 pupils.
