Police are looking for a group of men who threw chairs and punches during a brawl outside a cafe in busy Lygon Street in Carlton.

The fight broke out at a cafe near the Grattan Street intersection just after 11pm on Saturday, March 29 and forced diners to duck for cover.

One male bystander sustained minor injuries, police said.

The men had fled the scene when police arrived.

Police released photos of the men on Thursday, saying anyone with information about them or the fight should contact Crime Stoppers on 1800 333 000 or visit www.crimestoppers.com.au.
