Police warn fans ahead of AFL grand final

Victoria Police and the AFL are urging footy fans to be on their best behaviour at Saturday's grand final.

Assistant Commissioner Stephen Leane and the AFL's head of football operations, Travis Auld, said violent actions like last weekend's assault of a mother in the Perth crowd would not be tolerated.

About 200 police officers and 250 security personnel will monitor the 100,000-strong grand final crowd, with more police on duty during the festivities leading up to the game.
