Two men have been charged and a warrant issued for a third man more than seven years after members of the "Roast Busters" allegedly boasted on social media about having sex with drunk and underage girls.
The Roast Busters became notorious in 2013 when the group of mostly West Auckland teenage boys bragged on their Facebook page about alleged sex acts with girls as young as 13.
The saga raised questions about alcohol and the issue of consent and became a national scandal, when it emerged the police failed in the first instance to properly investigate complaints from several young women.
The publicity prompted a second investigation, Operation Clover, which identified 110 girls who had social contact with the so-called 'Roast Busters' - a play on the Ghostbusters film and a euphemism for a sex act.
Five of the girls made formal complaints to detectives, and the police were concerned about 25 others but they declined to make a formal statement.
