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 2014. 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.
