Two Collingwood supporters were removed from Perth’s Optus Stadium for brawling with other fans and security guards, after the final siren saw the West Coast Eagles take home the win for the qualifying final on Saturday, September 8.In this video, filmed by West Coast supporter Tanya Halse, two men in Collingwood merchandise can be seen attacking fans in West Coast jerseys, before scuffling with security guards who had arrived to remove them.Halse told Storyful the man in the Collingwood beanie had thrown a drink on the men he attacked earlier, left the area, and then returned after the final siren, which was when the scenes in the video took place.She said security escorted the men out, but the debacle had already ruined their celebration at the end of the game.This came after a string of other brawls and bad behaviours between AFL fans in 2018.
