AFL CHIEF executive Gillon McLachlan believes the recent spate of crowd violence "feels like an aberration" rather than a trend.

A third ugly crowd incident in a week at last Friday night's Western Bulldogs-Collingwood game – resulting in three fans being injured – saw Etihad Stadium officials ban one patron for life from the venue.

Police arrested and charged a 46-year-old man on a string of charges in the wake of the nine-person brawl.

Victoria Police acting commander David Clayton and Etihad Stadium CEO Michael Green confirmed at a media conference on Monday that extra security would attend AFL and other major events.

"It sounds defensive to say it feels like an aberration to me," McLachlan told 3AW on Friday morning. 

"But I go to a lot of footy and I go to the outer a lot – I wander around – and people are generally engaged in the footy, friendly and pleased to see you.

"They'll tell you what they think's right or wrong, but I've never seen this (violence).

"I'm hoping it's an aberration and we'll take the right measures with security to deal with it if there's something else going on, but I hope it's an aberration." 

Green said a review was underway at Etihad Stadium and they were "not ruling anything in or out", including reducing the percentage of alcohol content in the drinks available at the venue. 

McLachlan said the AFL was not considering a complete alcohol ban. 

"It just seems to me we don't need to go that far," he said.

"People should be able to have a glass of wine or a beer or whatever they want at the footy and you need to behave civilly, respect the other patrons and have zero tolerance to the behaviour – not the cause."

McLachlan also confirmed the AFL's general manager of inclusion and social policy Tanya Hosch was reviewing the League's racial and religious vilification policy. 

"It's Sir Doug Nicholls Round and Tanya Hosch is going to do a brief review of the rule, because it hasn't been done for a while and to see, in 2018, whether it needs to be expanded or changed," he said.

"I don't think it's a complete revamp – it's just a review … there's nothing screaming out that it has to change." 

The AFL Commission is on track to have an indigenous member by the end of the year.
