Largely no - the whole issue has been whipped up and no they are not 'Muslim gangs', the well-publicised issues involve people of different religious heritages.
Roterham child exploitation ring were commited by a gang of Pakistanis.
Oxford child exploitation ring were commited by a gang of Pakistanis.
The Derby child sex gang members (Said Zakaria, Abdirashid Abdulahi, Mohamed Dahir, Liban Abdi, Jusef Abdirizak, Mohamed Jumale, Abdulahi Aden, Arafat Ahmed Osman and Idleh Osman) were all Somalis.
The Telford child sex gang were 7 Pakistani men.
The Peterborough sex abuse case by Pakistanis, Roma and a Slovak (Oh, Look!!! Finally one! hahaha)
The Banbury sex gang was leaded by Mohamed Saleh and Said Saleh.
And the Aylesbury sex gang was leaded by an indian called Mohammed Imran.
Those are ALL mass rape cases that happened in the last 4 years in UK. All were totally or partially commited by who???
So Jon, get your facts straight.
