Angry Anderson's Son Allegedly Killed By 'Friend'

The son of Australian rock icon Angry Anderson died following a "bloody" assault.

Liam Anderson, 26, was found on a corner in Queenscliff, in Sydney's Northern Beaches, early on Sunday morning after sustaining critical head injuries.

Despite paramedics' attempts to revive him and an emergency services helicopter which arrived to transport him to hospital, he died at the scene.

A man was arrested at the scene and taken to Manly Police station for questioning. The 20-year-old is currently in custody and assisting police with their inquires.

Reports by The Daily Telegraph and Sky news allege the singer's son was friends with his attacker.

The Daily Telegraph has reported that friends said the Liam and his alleged attacker were 'obsessed with each other'.

"The man we have in custody was violent and it took a number of police officers to subdue and arrest him," Detective Inspector Michael Boutouridis told reporters on Sunday morning.

"Capsicum spray was used and significant force to arrest him. I don't know the circumstances leading to them being at the reserve this morning."

"It is a quiet area. The assault was brutal. It was quite a bloody scene."

Officers were called to a reserve on the corner of Pavilion Street and Bridge Road just after 6am, following reports of an assault.

When they arrived, "two people were found fighting".

Inspector Boutouridis said police are confident, 'in fact certain', the young man knew his attacker and the incident was not random.
