A Sydney man expected to be charged with the murder of Liam Anderson, the son of Australian rock musician Angry Anderson, will remain behind bars after a brief court hearing.
Another man was arrested at the scene and has been taken to Manly Police Station.
Paramedics and police from the Northern Beaches Police Area Command found the man, believed to be in his 20s, unconscious with serious head injuries.
He was taken to hospital immediately after he was restrained at the park by several police officers, as he allegedly attacked Anderson early on Sunday morning.
Mr Flame featured in Mr Anderson's social media posts, including in September at the Defqon.1 music festival.

Angry Anderson's manager, Scot Crawford, asked in a statement that media and the general public respect the family's privacy.
Friends of the 26-year-old gathered at the scene on Sunday afternoon laying flowers and handwritten notes.
Meanwhile, Angry Anderson flew home to Sydney from Perth overnight, where he had been performing. "The man we have in custody was violent and it took a number of police officers to subdue and arrest him", Det Isp Boutouridis told reporters.
"It's still early in the investigation but it's quite possible, yes", he said.
