James*, 16, screams as a pack of black-clad teenagers drag him to the ground and stomp on his head while an attacker films on his phone in Sydney's Strathfield Park

In another video, the gang forces a different 16-year-old into a toilet block and repeatedly punches him while calling him a "f*****" and a "kafir", or nonbeliever. Blood runs down his face as he begs, "I'll do anything"

A third clip shows a boy in a cropped top lying silent on the grass, his hands shielding his face as he is repeatedly stomped on and called a "gay dog", while one attacker shouts "Dawlatul Islam" — Arabic for Islamic State (IS)

"I'll f***ing shoot you, you little dog," one attacker says, before the victim finally emits a single high-pitched cry, and the video cuts out

Five teenagers have so far been convicted over the bashings

Several of them congregated around a radical Bankstown prayer hall, Al Madina Dawah Centre, which was ordered to close after the Bondi shooting

Police evidence connected members of the group to two of Australia's most influential pro-IS figures: spiritual leader Wisam Haddad and alleged youth recruiter Wassim Fayad
