Troublemakers at rugby league games could soon have their bans extended game-wide, following discussions between clubs.
There have been an increased number of incidents in recent years, most publicly at Salford recently, though also at Castleford, Warrington, Widnes and Wakefield to name but four.
Although bans have been handed out to perpetrators in some instances, they are usually limited to their clubs own venue.
However, steps are now being taken to introduce a centralised system, whereby anyone banned from one ground would subsequently be banned from all rugby grounds.
Details were revealed at a recent fans feedback session at Warrington by club chief executive Karl Fitzpatrick.
During the Wolves game at the Halton Stadium on Friday, a blue smoke bomb was thrown on to the pitch by someone in the Warrington end of the ground.
