MSK, 27, told the NSW Supreme Court yesterday that this was because the girls did not wear headscarves, were drinking alcohol and were unaccompanied when they went to his Ashfield home. MSK also blamed his intoxication, "cultural beliefs" and an undiagnosed mental disorder.

He and his brothers MAK, 25, MRK, 21, and MMK, 19 - who cannot be named for legal reasons - are serving between 10 and 22 years for raping two girls in 2002. All except MRK are yet to be sentenced for several other rapes.

Yesterday evidence was being heard on a sentence for MSK for the rapes of two more girls, TW, then 14, and CH, then 13. He admitted that some of the evidence he had given at an earlier trial was fabricated, particularly that he had had consensual sex with TW and that she had coaxed him.

"It was a pretty big untruth when you said that it was consensual sex, wasn't it?" asked the Crown prosecutor, Ken McKay.

"Yes," he replied.

You chose to lie about that, correct? - Yes.

During a long apology to TW, who was in court, he stopped mid-sentence to reprimand her.

"I wish to say this to [TW], that at the time when I commit these offences I come from such a background which led me to - don't shake your head, I'm telling you something - I say now that I hurt you and I'm extremely, extremely apologetic to you and I'm, I wish to say one thing more.

"I'm serving 22 years … I'm just requesting to you that you one day may come that you realise that the person who assaulted me is in prison … and I should forgive him. I'm asking for your forgiveness." He said it was only now, since he had gained a "better understanding of Australian culture", that he knew the rapes were wrong.

He arrived in Sydney for the ninth and final time four days before committing several rapes over six months. He had planned to study medicine.

He agreed he knew the girls did not want to have sex. "[TW] said no but I go ahead with it because I believe that at the time I commit these offences, I believe that she was promiscuous …" he said. "She don't know us, I don't know her, like she was not related to us and she was not wearing any purdah … like she was not … covered her face, she was not wearing any headscarf and she started drinking with us and she was singing.

"First off, I was actually, I was not taking my medication so I was under the influence of voices and secondly I believe at the time when I commit these offences that she had no right to say no."

Mr McKay said the voices excuse was a last-ditch strategy to avoid justice. "You wanted to hurt and terrorise these girls and you did that. You used acts of sexual intercourse on them."
