A video has emerged on Twitter of Geelong and Melbourne fans engaging in a brawl following the final siren of Saturday night’s thrilling contest between the Cats and Demons at GMHBA Stadium.

Zach Tuohy booted the winner for the home side after the siren, which saw Geelong overturn a 29-point final term deficit courtesy of eight straight final quarter goals.

However, moments after the siren sounded, fans from both clubs can be seen kicking, punching and pushing each other on the concrete steps, before other fans and security broke up the scuffle.

Victoria Police confirmed the incident to the Herald Sun on Saturday night.

“During the game one person was evicted at three quarter time and police are investigating one allegation of assault,” spokesman Sergeant Cameron Scott said.

“Police are aware of an altercation between spectators at the end of the game however, no one has reported any offences to police as a result of this incident.”

It follows on from a string of incidents at AFL matches over the past few months, with Etihad Stadium the scene of a pair of brawls back in May.
