Massive brawl breaks out between AFL Port Adelaide fans

A brawl involving fans of two AFL teams, during which one man cowardly punched another, has been caught on camera.
Spectators at Saturday night's Showdown match between the Adelaide Crows and Port Adelaide Power turned violent after the game finished at the Adelaide Oval.
Port Adelaide fans allegedly began spitting at rival Crows supporters before turning on one another and fighting on the stadium's hill.
The shocking footage begins with one man walking up to an unsuspecting fan before throwing a punch striking him squarely in the jaw.
The attacker appears to shout something at the victim before walking away.
More fans are then seen to engage in the brawl with spectators grabbing each other by the necks and yelling expletives.
At one point in the video a man approaches a shouting spectator and flings him to the ground by his scarf.
The man quickly stands up but his assailant is nowhere to be seen.
Security guards attempt to disperse the crowd from fighting but appear to be out-matched by the rowdy gathering.
Adelaide Crows players were still on the ground at the time of the incident, celebrating their 100-83 victory.
Users flocked to social media to express their disgust at the violent actions by some supporters.
'Bloody disgrace. Ban them all forever ever attending a game again and if they are members strip them off their honour,' one user wrote.
'Disgusting if you can't handle the beer and a defeat. Stay home instead of being a complete tool,' said another.
In a statement SA Police said that they are aware of the incident but have yet to lay any charges.
