The victim of a fatal stabbing in Light Square in Adelaide on Saturday morning has been identified as Christopher Hatzis.

Police say they are trying to track down about eight men who were involved in the brawl that ended in Mr Hatzis' death.

The 19-year-old Findon man died after he was stabbed during a fight on the eastern side of Light Square at about 2.20am on Saturday, near the Savvy Nightclub on Waymouth Street.

Police say the brawl followed a minor disturbance inside the Savvy Nightclub minutes earlier, after which the victim and another man were removed from the nightclub by security.

Detectives are continuing to analyse security vision from the club and surrounding areas, and police are asking for help from the public to identify people who were in the area at the time.

Police are trying to track down the men who were involved in the brawl in which Mr Hatzis was stabbed.

Detective Inspector Mark Trenwith from the Major Crime Investigation Branch said: "It may be that some of the men involved in this incident didn't realise that a knife was involved or that someone was going to be stabbed - if that is the case we would urge them to come forward and do the right thing by the victim and his family."
