The grooming gangs did not begin with white working class girls in the north of England but with girls of Sikh heritage in the West Midlands in the 1970's. Sikhs went to the police and met with an indifferent response eventually forming themselves into vigilante groups. The resulting street violence was dismissed by police as 'inter-community tensions'.

You are far too charitable to the perpetrators. The grooming gangs represent one of the longest-running criminal enterprises in UK history - literally decades of men from a particular background targeting young women of different ethnicities. This goes way beyond mere sexual frustration.
