A Western Sydney Wanderers fan let off a flare at Perth Glory, narrowly misses the roof [Vine]

There was almost a major safety incident in the A-League over the weekend.

The Perth Glory beat the Western Sydney Wanderers 3-2 over the weekend, while the visitors brought a passionate group of supporters with them to the away match.

Known as the Red and Black Bloc, or RBB for short, one fan came close to causing some serious damage when he let off a rocket flare in the stadium.

The incident was caught on a fan cam, with the flare narrowly missing crashing into the roof of the stadium.
