The graphic film, parts of which were aired last night on Channel Seven's Today Tonight, reportedly shows the semi-naked girl — who has a mild developmental delay — performing sexual acts on a gang of up to 12 youths who then set her hair on fire and urinate on her. The DVDs, which have been sold in secondary schools in Melbourne's west for $5, also show the boys making chlorine bombs, dropping flares on a homeless man and throwing eggs at taxi drivers.

Police yet to see DVD A Victoria Police spokesman said police were told only yesterday about the alleged sexual assault, by the alleged victim's father. "I confirmed that myself when I spoke to detectives today, Werribee police were not informed until yesterday morning and that was the first we had heard about it,'' the spokesman said.

"We (also) got a phone call from a teacher yesterday morning passing on second-hand information they had heard about the existing DVD and that Today Tonight were doing a story on it. The investigation into the alleged attack would not start until police obtain a copy of the DVD.

"The investigation hasn't started. We're obtaining a copy of the DVD today which will commence an investigation in relation to the DVD and the father of the alleged victim of the assault will be taking her to Werribee police today to make a statement in relation to the incident and that will be the start of that particular investigation." Father's plea The father of the alleged victim has pleaded for all copies of the DVD to be destroyed.

"Alan", the father of 17-year-old victim "Julie", called on parents whose children possessed the DVD to destroy it. "I'm almost begging parents to do this. This has such implications for my daughter's future," he told Southern Cross Radio.

Julie arranged to meet two of the boys through an internet chat service at a Werribee shopping centre, but soon after arriving she was surrounded and forced by a gang of up to 12 to a nearby riverbank, where the attack took place, Alan said. "She's very ashamed. She was hoodwinked, tricked, manipulated into this and it's all happened within five or ten minutes," he said. Daughter 'traumatised'

"She is very traumatised by this." Channel Seven had told him that parents of the boys who produced the DVD laughed it off as "just a bit of fun".

"They need to know that that is not a bit of fun," he said. "They've caused us great grief," said Alan. He said the attack was a warning to parents of the dangers of the internet. "Start listening to what some of the professionals are saying about the problems that can occur," he said.

Bracks condemns attack Victorian Premier Steve Bracks has described the assault as "horrendous".

"Frankly I'm appalled, and it's behaviour that the whole of Victoria will reject," Mr Bracks said while making a transport announcement in Mitcham. "This is a horrendous act on someone who was obviously very innocent, someone who was being led into this situation. This (is) illegal behaviour which I reject totally, and I think the whole community will be appalled by that." Credits name boys

Senior Sergeant Paul Mullett, secretary of Victoria's Police Association, watched excerpts of the video yesterday. "This is nothing short of disgraceful behaviour. What I have seen is reprehensible behaviour," he said.

The names of some boys involved were listed in the DVD's credits, he said. "They are really not very smart because they have identified themselves by name and in person." Sergeant Mullett called for the "full force of the law" to be brought against those involved.

The principal of Kardinia International College, in Geelong, said tonight that one boy had been expelled over his role in producing the DVD. Principal John Goodfellow said he was not aware of the DVD or its contents until yesterday, and a school investigation would take into the actions of two other male students who "may have had some involvement".

Mr Goodfellow told the Nine Network tonight that he had spoken to the expelled teen. "No, he wasn't really trying to defend himself, he knows he did a very, very silly thing," Mr Goodfellow said. "(But) I don't think he understood the full extent and the consequence of the stupid, horrid video."

Mr Goodfellow said the Geelong school community was unified in its support for the young woman involved. "We're absolutely shocked and we feel very sad and sorry for the girl concerned ... what has happened is absolute stupidity and also very, very miserable."
