Girls were “left at the mercy” of paedophile grooming gangs for years because of failings by senior police and council bosses, a report has said.
The review covers 2004 to 2013 and sets out a series of failed investigations by Greater Manchester Police (GMP).
It also highlights the apparent local authority indifference to the plight of hundreds of youngsters identified as potential victims of Asian men.
GMP has apologised and said such cases were handled very differently now.
The report also identifies 96 men still deemed a potential risk to children, adding that this was “only a proportion” of the numbers involved in the abuse.
Greater Manchester mayor Andy Burnham has since called for disciplinary action to be taken against police officers and council officials who “failed in their duties” as well as some prosecutors in the North West.
He also praised whistleblowers, including health worker Sara Rowbotham and former GMP detective Maggie Oliver, who raised concerns despite facing vocal criticism from authorities.
In 2007, Ms Rowbotham and her team had alerted GMP and Rochdale Council about a gang of men of Pakistani and Afghan heritage engaged in child sexual exploitation (CSE) while Ms Oliver resigned from GMP in 2012 to publicly reveal the extent of the police failings.
Mr Burnham commissioned a series of independent reviews following the 2017 BBC documentary The Betrayed Girls, which highlighted repeated failures to protect children in the region.
One child victim, known as Amber, gave “significant evidence”, but the crimes were not recorded by GMP and perpetrators were potentially left to continue their abuse of other children, the report found.
Amber was even described as a co-conspirator in the sexual exploitation of other children in one trial without her knowledge – an allegation which she always denied and was unable to defend herself against.
