Police want to speak to anyone who saw a bust-up in Kensington Place on Saturday 12 June, in which one of those involved allegedly had a knife.
Two men have been arrested. One of them, 31-year-old Marco Paulo Do Nascimento, appeared in the Magistrate's Court earlier this week charged with grave and criminal assault and possession of an offensive weapon.
He's been bailed following the incident just before 11pm near the junction of the Wagon Wheel Cafe.
Officers were called to the scene following reports of people shouting and screaming.
Police say the knife was in one of the men's pockets and was recovered safely. No one was hurt.
Anyone with information on what happened is asked to call police on 612612 or Crimestoppers anonymously on 0800 555 111.
