A FATHER and son have been charged over the bashing of a boy in South Australia’s Port Augusta.

On Monday morning a 45-year-old man and his 14-year-old son allegedly confronted a teenager known to them — and shocking video of the altercation has been posted online.

Video circulated on Facebook shows a teen attacker egged on by an older man as the victim is hit and kicked while on the ground.

Police say the teen, who was unhurt, knew his attackers.

The older man is heard telling the alleged victim he will “punch his face in” if he defends himself.

“Tell him to leave me alone then,” the boy shouts in the footage that emerged yesterday.

“No. You deserve what you get, mate,” the man tells him.

He goes on to threaten to find the boy at his home. “I am going to come to your … house, mate, and there’s gonna be … hell. You got it?”

The man demands the victim “apologise” before he is dragged to his knees, then telling him: “You spit on my daughter again and I am going to cave your head in.”

The 45-year-old was bailed to appear in the Port Augusta Magistrates Court on January 2, while his son will appear in the youth court the following day.
