Teen busted with knife and fake gun outside AFL match

The teen, who arrived without a ticket and was unable to get into the game, was searched by nearby officers, who found he was carrying a small knife and a fake gun.

Police issued the youth with a caution.

The AFL has been contacted for comment.

It is the second time the AFL has been rocked by a weapons incident after two men were allegedly caught with guns at a Carlton-Collingwood clash with more than 82,000 fans at the Melbourne Cricket Ground in April.

The weapons were discovered after the pair, who were on bail, refused a security request to leave the venue due to their behaviour.

Officials blamed the incident on a "breakdown" in screening measures.
