Seems like a number of fans couldn't help themselves and decided to act like morons. Just having a bit of fun or stupid twits? This behaviour doesn't do good for anyone especially the club.
Rowdy Tigers fans flood Melbourne streets
Police have moved in to control rowdy Richmond Tigers fans flooding Melbourne's Swan Street after as fans set off dozens of flares.
One fan took his passion to the extreme as he climbed on the roof of a nearby store on Swan Street in Richmond and set alight a cardboard sign mocking Greater Western Sydney player Toby Greene.
Many fans took to the streets to continue celebrating after watching the Tigers' triumphant win over the Giants at the MCG.
But celebrations quickly turned chaotic with police arresting dozens of fans outside pubs and in streets.
