A gang of twenty men have been found guilty of sexually abusing girls as young as 11 in Yorkshire between 2004 and 2011.
The group were convicted of more than 120 offences against 15 young girls in the Huddersfield area following their "campaign of rape and other sexual abuse".
The case can be reported for the first time today after a judge lifted a reporting restriction imposed on the series of trials almost 12 months ago.
Three trials at Leeds Crown Court this year have heard how more than a dozen vulnerable teenage girls were plied with drink and drugs and then "used and abused at will".
Those already sentenced have received prison terms totalling 221 years.
The group's ringleader Amere Singh Dhaliwal, 35, was jailed for life and told he must serve a minimum of 18 years in prison by a judge who told him: "Your treatment of these girls was inhuman."
Dhaliwal was jailed for life earlier this year and told he must serve a minimum of 18 years in prison by judge Geoffrey Marson QC who said: "Your treatment of these girls was inhuman."
Dhaliwal, who has children of his own, was convicted of 54 separate counts, including 22 rapes, involving 11 different girls.
The judge told him earlier this year: "You treated them as commodities to be passed around for your own sexual gratification and the gratification of others.
"The extent and gravity of your offending far exceeds anything which I have previously encountered."
The judge went on: "It was a very significant campaign of rape and other sexual abuse.
"Children's lives have been ruined and families profoundly affected by seeing their children, over months and years, out of control, having been groomed by you and other members of your gang."
At the end of the first trial, the judge said: "The way you treated these girls defies understanding; this abuse was vile and wicked.
"As cases of sexual abuse with which the courts have to deal, this case comes at the top of the scale.
"None of you has expressed any remorse for what you did."
He added: "The sentences I pass on you are severe and are intended to be so. They are intended to deter others from behaving in this way."
The Huddersfield grooming trials were allegedly put at risk by the antics of English Defence League founder Tommy Robinson, who flouted reporting restrictions designed to ensure the proceedings were fair.
Robinson, a convicted fraudster who has also served time for assault and drugs offences, claimed the activities of the gang were being covered up because the offenders were of Asian origin.
Home Secretary Sajid Javid said: "These horrific crimes are sickening and, first and foremost, I commend the bravery of those who've suffered abuse in coming forward.
"I thank both the police and the Crown Prosecution Service for their dedication and I am glad to see these offenders face justice.
"I've made a personal commitment to tackle child sexual abuse in all its forms and the significant investment we have provided to transform law enforcement's response is beginning to take effect.
"I am prepared to ask difficult questions about these types of offenders and I will not stop until we have done everything possible to protect vulnerable children."
