A suspected member of the Roast Busters has reportedly skipped town over accusations of his involvement of the Facebook group in New Zealand, bragging about having sex with young girls while they are drunk.

Roast Buster Joseph Parker has allegedly left after abuse and threats were directed at his family home. According to reports, the parents of Mr Parker defended the actions of their son despite the videos of their son on Facebook showing him and his friend bragging about their sexual escapades with young and drunk girls.

The Parker family insisted he did the right thing and "fronted up to police" when he realised the sex had gone too far. A 13-year-old girl has come forward and said three boys had group sex with her. When the girl did not consent to the activity, the young Parker pulled one of the boys off her and said they had gone far enough.

The young Kiwi girl told her family about the incident and filed a complaint with the police. Upon learning the news, the girl's older brother went to Mr Parker's house in West Auckland to confront him about the incident, but he was told the boy was away.

According to a family friend of the Parkers, the boy's stepfather took him to the police to make a formal statement upon his return.

More than 63,000 people sign petition

Meanwhile, over 60,000 people have signed an online petition, urging New Zealand Prime Minister John Key to do something about the Roast Busters controversy.

In the petition, the people called for Mr Key to take sexual violence seriously and bring justice to the young victims of the teen rape club, Roast Busters. Auckland mum Jessie Hume set up the online petition on Nov 7. It currently has 63,000 people supporting the call for action.

Ms Hume said that the New Zealand government, authorities and the legal system have failed the young girls. She said the online petition seeks justice for the victims and called on the government to ensure it does not happen again.
