The Rochdale child sex abuse ring involved underage teenage girls in Rochdale, Greater Manchester, England. Nine men were convicted of sex trafficking and other offences including rape, trafficking girls for sex and conspiracy to engage in sexual activity with a child in May 2012. This resulted in Greater Manchester Police launching Operation Doublet to investigate further claims of abuse with 19 men so far being convicted. Forty-seven girls were identified as victims of child sexual exploitation during the police investigation. The men were British Pakistanis, which led to discussion on whether the failure to investigate them was linked to the authorities’ fear of being accused of racial prejudice. The girls were mainly White British. In March 2015, Greater Manchester Police apologised for its failure to investigate the child sexual exploitation allegations more thoroughly between 2008–10. Sara Rowbotham, the sexual health worker who first recognised patterns of child abuse in the community and fought to bring these crimes to police attention, was made redundant in 2017. A former Detective Constable who was investigating the grooming gangs, Margaret Oliver, resigned in 2012 in disgust of the handling of the cases by the police force and spoke out as a whistleblower to inform the public.
