They found a man suffering from stab injuries who was treated at the scene but later died in hospital.
A statement said: “Enquiries continue to trace the suspects, who fled the scene. There have been no arrests. A crime scene is in place. The incident is not believed to be terror-related.”

Bahir Moulana told the Press Association that as he was walking towards the mosque police were pushing people back before closing the main gate.
Referring to recent attacks at two mosques in New Zealand, the 39-year-old said: “I saw all the blue lights and my heart was in my mouth.”
With worshippers eventually let out of the building, he added: “There was one girl who said she saw two guys run in. Someone else told me the police were chasing them.”
Karen Buck, Labour MP for Westminster North, said of the attack: “Deeply saddened to hear this awful news. Police have been in contact with me and we await further details.”
