An investigation into the sexual abuse of underage girls in the Manchester area allowed a large network of paedophiles to operate for years.
One of those girls was 15 year old Victoria Agoglia. A report's found social workers knew she was being raped and forcibly injected with heroin, but they failed to help her. She died just two months later.
Greater Manchester Police and Manchester social services are apologising for their failures. Their investigation was closed 17 years ago despite dozens of girls giving evidence about abuse by Asian men.

Meanwhile Greater Manchester Police have apologised to victims of Operation Augusta.
The assurance review of the investigation into 'grooming gangs' in Greater Manchester was ordered by Andy Burnham.
Chief Constable Ian Hopkins said: "On behalf of Greater Manchester Police I want to apologise to all of those vulnerable children, who were let down in 2004 when Greater Manchester Police did not thoroughly investigate the abhorrent offences that had been committed against them."
He added that one man had been arrested and another interviewed under caution as part of the new investigation into child sex abuse in Greater Manchester.
Both of the men have since been released under caution.
