A 44-year-old man was stabbed to death in a daylight stabbing on a Paceville street on Monday afternoon.
Police said the man, a national of Romania, was stabbed with a "sharp object" at around 3.30pm on Ross Street.
They believe the incident kicked off when a group of men began arguing. The argument escalated and the victim was stabbed in the ensuing fight.
Those responsible fled the scene before the police arrived, and a manhunt is now underway for the aggressors, a police spokesperson said.
Police are treating the case as a homicide.
The victim was rushed to Mater Dei Hospital but died shortly after being admitted.
Magistrate Charmaine Galea is leading an inquiry into the case.
