Later, as Tigers fans poured into Richmond's Swan Street, three were arrested for public drunkenness and another three will appear in court on summons for discharging flares.

In another incident at 5.45pm, police arrested a 21-year-old Brookfield man who allegedly bit a police officer, and a 27-year-old Brookfield man who police say struck a second officer to the back of the head, after the pair were spoken to by police about their behaviour.

Both men were charged with assaulting police and public drunkenness, and were released on bail.

The police officer who was bitten in the incident was taken to hospital for treatment.

Fifteen people in total were removed from the football ground for public drunkenness.

Revellers flooded Swan Street for an impromptu street party after the grand final finished at the 'G, resulting in six arrests.

Three people were arrested for public drunkenness, while another three will appear in court on summons for discharging flares.

Police said despite the behaviour of a few people on Swan Street, they were generally happy with the behaviour of footy fans celebrating the Richmond win overnight.

A man who held up a burning poster of Greater Western Sydney player while standing on an awning was met by police after climbing down.

Just nearby, at the corner of Lennox and Swan streets, another man who set off flares into the street still teeming with revellers was marched away by officers.
