Three years ago, a Crown Prosecution Service lawyer dropped a rape case involving an under-age girl which could have left a sex grooming ring undetected for years.
The teenager was arrested outside a takeaway in Heywood in August 2008 for being disruptive.
She alleged one of the workers had groomed and then raped her.
Greater Manchester Police (GMP) investigated Kabeer Hassan and another man, aged 59, but it was nearly a year later when a CPS lawyer decided to drop the case.
According to Nazir Afzal, chief prosecutor for the North West, the lawyer had viewed six hours of video testimony from the girl and also had DNA evidence, but decided "she would not be viewed as a credible witness by a jury".
