A teenage girl was today jailed for luring a 16-year-old to a house party where she was plied with drink and drugs before being gang-raped at knifepoint.
Amber Roderick, 19, smothered herself in dog shampoo and joined in with the horrific attack which left the vulnerable victim traumatised.
Today it emerged that she had only just been released from jail after forcing two boys, aged nine and ten, to perform s*x acts on each other in a park.
Jailing her indefinitely for at least four years, Judge Bruce McIntyre said she posed a significant risk of harm to the public, including young people and children.
Roderick had met the 16-year-old in the street and later persuaded her to join a party which was being thrown by her friends.
She was given cannabis as well as vodka and coke drinks so strong she had to ask for them to be watered down, Reading Crown Court heard.
The initial assault took place on the top floor of the house, in Reading, where Joseph Lawrence, 29, threatened the girl with a knife before forcing himself on her. Roderick also took part in the attack.
After the pair had finished, Lawrence told his young victim that he would stab her in the face if she ever told anyone.
But her horrific ordeal was not over. She managed to free herself and tried to flee to the bathroom. But she was caught by 26-year-old Patrick Maughan, another party-goer, and Roderick, who subjected her to another assault.
It was at this point that Roderick rubbed dog shampoo over her own body as she carried out the attack.
The horrifying act lasted less than 10 seconds but the victim told Reading Crown Court it left her feeling physically sick and shattered.
She eventually managed to escape from the house and informed police.
Her attackers were arrested while they were still drunk at the party, which was held at Lawrence's mother's house on April 3 last year.
The court heard how even in police cells Roderick was heard threatening to kill her victim.
Roderick refused to appear before Judge McIntyre to be sentenced today and stayed in the cells beneath the court room.
In her absence, she was jailed indefinitely with a minimum term of four years.
Judge McIntyre said that Roderick posed a 'significant risk of serious harm to the public, including children and young persons and that is likely to remain the position until she addresses her offending behaviour.'
And he revealed that she had been found guilty of 'similar bullying s*xual abuse before'.
'Ms Roderick has chosen not to tell anybody who might have told me what has happened in her short life to make her the way she is,' he said.
'However, in Ms Roderick’s case I am quite satisfied that as a result of these offences and her previous convictions for s*xual abuse of young boys, taken together with her attitude to anybody who challenges her about this offending behaviour, that she is dangerous.
Addressing Lawrence, he said: 'It was a prolonged period of time during which she was kept in that house.
'You did not use a condom. You threatened her afterwards using words to the effect that she might get stabbed in the face if she told anybody what had happened. You showed no remorse.'
Maughan was jailed for six years while Lawrence, from Reading, was given seven years.
The pair smiled and waved at weeping family members as they were led down to the cells.
Maughan kissed his partner through the glass around the dock as she wailed 'Patrick' before he was taken down.
All three had been found guilty after a trial in December. The verdicts sparked violent scenes in court in which Roderick attacked security guards.
