Football Federation Australia Chief Executive David Gallop has released a statement following last night's Hyundai A-League match between Melbourne Victory and Western Sydney Wanderers.
"The behaviour of some fans and in particular a section of the Western Sydney Wanderers fans at last night's match was unacceptable and will not be tolerated," said FFA CEO David Gallop. "FFA is currently compiling all reports from Victorian Police, stadium security and both clubs before deciding what action to take.
"This is a clear reminder of the type of people we do not want in our game and that will be reflected in the final outcomes of our enquiries.
"FFA is currently undertaking a review of the security and banning procedures to ensure a fair process for fans who are identified as misbehaving but will not waver from protecting the safety of spectators.
"Finding that balance during the banning process is central to our review but last night's events should be a reminder that the actions of a minority can damage the reputation and image of the game. That is why we will continue to identify and ban troublemakers."
