A TEENAGER remained in police custody last night after a brawl erupted in the stands of the Roosters and Bulldogs match at Allianz Stadium.

The fight broke out in the member’s stand of the Moore Park venue during the second half of the NRL match, with Channel Nine commentators Ray Warren and Gus Gould commenting on the people brawling right in front of the commentary box.

Police said a man was knocked to the ground when a fight broke out involving a group of youths about 9.45pm.
