Three of the five males accused of gang-raping a 16-year-old girl in Sydney's west will remain behind bars until their next court date.
Four men aged in their 20s and a 17-year-old boy have been charged over the multiple assaults that allegedly took place in St Clair in May.
They were charged after police found footage of the attack on a GoPro camera seized as part of an investigation into graffiti.
"I had a number of my investigators looking at this and they were horrified at what they saw in this footage," Detective Chief Inspector Peter Yeomans from the Child Abuse Squad said on Thursday.
"It's horrible. It's terrible what happened to this young girl."
Kurt Stevenson, 24, didn't apply for bail when brought before Penrith Local Court on Thursday morning, facing three charges of aggravated sexual assault in company.
It was formally refused and he will remain in custody until he appears before the same court on December 10.
One of his co-accused, 23-year-old Andrew Waters, has been charged with aggravated sexual assault in company and aggravated indecent assault in company.
Waters didn't apply for bail and has been ordered to reappear before Penrith Local Court on the same day as Stevenson.
Tristan Carlyle-Watson, 25, has been charged with concealing a serious indictable offence over the incident and was formally refused bail after not applying.
He is due to return to Penrith Local Court on December 11.
Another man, 24, is set to front court later on Thursday.
The 17-year-old's case is set to be heard on Thursday as well.
The victim was either unconscious or semi-conscious at the time and the attack was not reported, but officers had since contacted and interviewed her, Det Chief Insp Yeomans said.
She is undergoing counselling.
