Three men have been found guilty of raping a 16-year-old girl and filming the assault with a GoPro camera during a house party in Sydney, Australia. Kurt Stevenson, 26, Andrew Waters, 24, and Tristan Carlyle-Watson, 26, were convicted of aggravated assault in company at the Downing Centre District Court.

The defendants, who denied the charges, are due to be sentenced in October. The victim, whose identity has not been disclosed, was raped at a house in St Clair, Western Sydney, in May 2015. Prosecutor Sharon Harris said the victim had drunk alcohol and smoked cannabis and had asked one of the men to take care of her as she did not know anyone at the party.

The defence argued the group sex was consensual and the 17-minute-long video found on the GoPro shows the victim enjoying it. However, the defence said the victim was too intoxicated to provide consent. Harris explained the men raped the victim "sometimes... simultaneously, sometimes taking turns", local news site reported.

In the video, one of the men is heard saying: "One by one we'll all get a f**k." The victim had "slow movements, floppy limbs", and repeatedly said she was tired and wanted a blanket, Harris explained.

"Kurt Stevenson has to direct her to take her clothes off or to move or sit up," she said. "They don't speak to her other than Kurt Stevenson who seems to be, you might think, pacifying her."

The victim was not aware of what had happened to her until a few weeks later, when police contacted her after finding a GoPro with the video of the assault. However, the victim said she remembered going to the bathroom and finding lot of blood, reported.

When a friend came to pick her up, the victim was naked and covered only by a towel. The GoPro footage was found by the police as they were conducting an unrelated operation.
