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.
