A second watchdog review into which senior cop shelved an investigation into a south Manchester child sex grooming gang has failed to identify which officer pulled the plug, or the reason why.
At least 57 children and young girls - many of them in care - were raped and abused by up to 100 members of a gang of Asian men 18 years ago.
Two years ago a damning report commissioned by Greater Manchester Mayor Andy Burnham revealed it failed to establish which senior cop pulled the plug on Operation Augusta. Now, it has emerged the police watchdog has also failed to establish their identity after conducting its own two-year probe.
