Following the trial the police, questions were raised about the cultural backgrounds of those involved, and whether this had allowed exploitation to flourish.
The Crown Prosecution Service (CPS) and the local council in Rochdale were heavy criticised when it emerged that the girls who complained were not listened to amid a catalogue of systematic failings.
Police and social workers were accused of failing to tackle the issue for up to a decade.
A chance to stop the gang was missed in 2008 and both the police and the CPS were forced to apologise for their failings while Rochdale Council said it "deeply regretted" the missed opportunities.
The Independent Police Complaints Commission (IPCC) is now investigating the botched inquiry.
The first victim, who was 15 when the abuse began, told the police what had been happening in August, 2008, but her complaint was not taken seriously and she continued to be abused by the gang until December 2008 when she fell pregnant and moved away.
In July 2009 a CPS lawyer then compounded the police failure to take her seriously and made the decision not to charge the two gang members she was accusing because he did not think a jury would find her "credible".
After the trial, she said she was "let down" by police and the CPS because the issue of Asian gangs grooming young white girls was "unheard of" at the time.
She said the problem got "worse" after telling the police.
"It's like, then, in 2008 it weren't really heard of ... Asian men with white girls.
"It was just unheard of. I've never heard of it. Now it's going on everywhere," she said.
The offences happened in and around Rochdale in 2008 and 2009.
The five girls - aged between 13 and 15 - were given alcohol, food and money in return for sex but there were times when violence was used.
Police said the victims were from "chaotic", "council estate" backgrounds and as many as 50 girls could have been victims of the gang.
The gang received jail sentences of between four and 19 years from a judge who said they treated their victims "as though they were worthless and beyond any respect".
In comments which appeared to conflict with police insistence that there was no "racial or cultural" element to the crimes, Judge Gerald Clifton told Liverpool Crown Court: "One of the factors leading to that was the fact that they were not part of your community or religion."
The judge said some of the men claimed their arrest "was triggered by race".
But, he said: "That is nonsense. What triggered this prosecution was your lust and greed."
Despite the comments from Judge Clifton, Greater Manchester Police denied there was a "racial or cultural" element to the gang's crimes and said it was about adults abusing vulnerable children.
The men were convicted of conspiracy to engage in sexual activity with children under the age of 16 and other sexual offences including rape and trafficking for sexual exploitation.
Shabir Ahmed, 59, - the man regarded as the ringleader - was jailed for a total of 19 years for conspiracy, two counts of rape, aiding and abetting a rape, sexual assault and a count of trafficking within the UK for sexual exploitation.
The defendant was banned from the court because of his threatening behaviour and for calling the judge a "racist b------".
The judge called Ahmed an "unpleasant and hypocritical bully".
