Officers attended along with London Ambulance Service and London Air Ambulance medics. A 23-year-old man was found with a stab injury to his back. Despite the best efforts of the emergency services he was pronounced dead at the scene.
While formal identification is yet to take place, officers believe the victim was Ian Gualavisi, a restaurant manager who had lived in London since birth.

Officers from the Met’s Specialist Crime Command have begun a murder investigation and are appealing for anyone with information about the attack to come forward.
Detective Chief Inspector Chris Wood said: “A dedicated team of officers is working round the clock to trace those responsible for taking Ian’s life and my thoughts are with his family as they come to terms with their tragic loss.
“While we remain in the early stages of the investigation, we believe Ian was attacked by two men who left the scene on a moped towards Elephant and Castle Railway Station.
“We are in the process of collecting CCTV from the area and speaking to people who were nearby at the time of the attack. I would urge anyone who hasn’t spoken to us yet to contact police as soon as possible.”
