Another woman, Hannah Sims 21, who was renting the Hastings flat at the time, has pleaded guilty to nine charges, two charges of indecent assault, sexual violation and assault with a weapon, as well as a charge of injuring with intent to injure, threatening to kill and unlawfully detaining a person. During the trial yesterday, Roper became increasingly agitated when Crown solicitor Steve Manning suggested she was in it "boots and all," encouraging the attack on the victim.
She admitted she "hurt" the girl but said: "I did not do everything."
Mr Manning suggested Roper and her co-offenders had "got their heads together" to come up with a story to protect them all. She denied this.
Roper insisted she was not there when the girl was violated with bottles.
"I've owned up to what I've done."
She said the victim was lying when she claimed Roper was standing over her when she was violated.
She told Mr Manning she didn't want to watch video footage that she shot on her cellphone of the victim being stripped naked and having water thrown over her.
"I want to go. I don't want to watch it," she said.
Judge Geoff Rea told her: "You'll do as you're told."
The judge then asked that lawyer Roger Philip talk to his client about her behaviour. After a short adjournment, Roper watched the footage and continued to answer questions put to her.
Meanwhile, her co-accused Kerr spent most of the afternoon visibly distressed while listening to the defence case.
Olsen was the next co-accused to take the stand. He told the court he knew nothing about the sexual violation until the next day.
"I was pretty wasted."
He did tell police during an interview he saw the girls fighting and told them to take their pants off.
"When you see two chicks fighting, you want them to get naked," he said in the interview played to the court.
The trial continues today.
