A 23-year-old man was stabbed to death on Thursday night after a fight broke out in Marsa at around 10pm.
Medics from Mater Dei were called to the scene to treat the victim, who was found unconscious and lying face up in a pool of blood, police said. But he died before he could be taken to the hospital.
Police said two men, both from Ghana, were involved in a fight on Triq it-Tiġrija. The 25-year-old alleged aggressor was tracked down to a house in Triq Azzopardi at around 1.30am on Friday but tried to escape arrest by running over rooftops.
He was eventually apprehended and the murder weapon, believed to be a knife, was found under a tree in Triq il-Jum.
The murder is the first this year.
Investigations are ongoing, with duty magistrate Gabriella Vella leading an inquiry.
