Rowdy soccer fans in Melbourne let off more than four flares, with heavy orange smoke flooding a stadium at a match between Melbourne Victory and Western Sydney Wanderers on Saturday.
AAP reports fans at the game took to Twitter to express their concern after hearing at least five explosions at AAMI Stadium about 9.30pm (AEDT).
"Anyone would think terrorists have overtaken AAMI," said one message.
Another fan tweeted: "kids and parents were walking out scared".
Earlier, soccer fans set off flares, broke chairs and glasses and threw sticks in a brawl outside the Royal Melbourne Hotel on Bourke Street just after 3.30pm (AEDT) on Saturday.
Police said at least four people were injured in the scuffle. No arrests were made.
