Six people, including three brothers and their uncle, have been convicted of the “systematic” sexual abuse of teenage girls in Rotherham.
Brothers Arshid and Basharat Hussain were found guilty of multiple rapes and indecent assaults in the South Yorkshire town.
A third brother, Bannaras Hussain, 36, admitted 10 charges including rape and indecent assault prior to the trial.
Their uncle, Qurban Ali, 53, was found guilty of conspiracy to rape.
Two women, Karen MacGregor, 58, and Shelley Davies, 40, were convicted of conspiracy to procure prostitutes and false imprisonment.
During the trial, jurors heard how 15 victims were “targeted, sexualised and in some instances subjected to acts of a degrading and violent nature” between 1987 and 2003.
Arshid Hussain was found guilty of 23 of the 28 charges he faced, while Basharat Hussain was convicted of all 15 charges.
Ali was found not guilty of charges of rape, indecent assault and procuring a girl under 21 to have unlawful sex with another.
Majid Bostan, 37 and Sajid Bostan, 38, who are also brothers, were cleared of all charges at Sheffield Crown Court.
Some of the women abused by the gang sat in the court as the verdicts were returned by the jury, some holding hands with each other.
Det Ch Insp Martin Tate said the verdicts were a “crucial milestone for those victims who have endured years of violence and horrific sexual abuse at the hands of these vile individuals”.
He said: “I can’t begin to put into word the trauma that these women experienced at such a young age.
“I’m pleased that their voices have finally been heard and believed and that those responsible have been publicly held to account for their crimes.”
One victim, who is now 43, went to live with MacGregor after she was befriended by her and Davies in the late 1980s.
While she lived there, she told the court, men were brought to the house and she was told to have sex with them in exchange for being looked after.
A second woman, now 36, was subjected to regular sex attacks by Arshid Hussain – also known as Mad Ash – who passed her round to other men when she was in the care of the local authority.
Peter Mann, from the Crown Prosecution Service said: “These defendants in their differing ways targeted these teenage girls because they were vulnerable and then facilitated their systematic sexual abuse.
“They were mocked and spat at, some of the violence was extreme and protracted.
Arshid Hussain in particular had “played a key role” in the abuse, Mr Mann added.
“He was domineering and in some instances brutal in his treatment of the girls.
“He used them for his own gratification then often prostituted them or passed them on to his brothers or associates.”
A youth worker in the town, who wrote an unpublished report for the Home Office in 2002 on child sexual exploitation, said the men had considered themselves above the law.
Adele Gladman said: “They were being allowed to do it completely unchallenged and I think that did definitely give them a feeling of invincibility.
“I don’t think I have ever encountered the levels of sadism and torture and sheer cruelty that we were encountering against children.”
