It seems 11 suspects associated with 13 complaints over three years were never really investigated at all.
An investigator from the Metropolitan police specialist sex crimes unit has admitted failing to investigate the alleged rapes and sexual assaults of 12 women by faking police reports, failing to pass on forensic evidence and not interviewing suspects.
It was the Sapphire Unit, which were supposed to set the gold standard for exemplary investigation of sexual crimes for the rest of the country's forces.
