Drunk racegoers sparked a mid afternoon mass brawl when they picked a fight with a passing driver.
Video footage from another driver shows two groups appearing to face off outside a pub in Doncaster town centre.
The video was filmed on Saturday evening, after the St Leger Stakes Race.
The fight is alleged to have started when the pub goers became rowdy and spat at the passing red Volkswagen Golf.
The video shows the group in shirts and suits shouting angrily at the driver and his passengers.
A woman in white stilettos and a pink suit tries to hold back the man in a beige shirt.
