City of London Police continue to hunt for the suspect who stabbed a man to death between Leadenhall Street and 30 St Mary Axe in the capital's financial district after a party ended in tragedy.

Officers were called shortly after 3am on Sunday (6 December) to Leadenhall Street to reports a man had been stabbed. Reports suggest that a group of black males were seen arguing inside Caravaggio restaurant on Leadenhall Street.

The group then left the venue and fighting took place in Leadenhall Street and St Mary's Axe, where the 23-year-old victim was stabbed. Officers and London Ambulance Service attended and rushed the man to Royal London Hospital hospital suffering stab wounds to the abdomen. He died at 3.41am on Monday (7 December).

Four men aged between 24 and 28 were arrested close to the scene but have since been released on bail. Detective Chief Inspector John Osibote of the Major Crime Team said: "I would appeal to anyone who witnessed the argument inside Caravaggio or who saw a group of black males fighting in Leadenhall Street to come forward and speak to detectives. The victim went out on Saturday night to attend a party and has lost his life in a needless violent act."

Anyone with information is asked to call detectives on 0207 601 2988. Your information will be dealt with in the strictest confidence. If you wish to remain anonymous then call Crimestoppers on 0800 555 111.

Police said murders in the Square Mile were rare, with the last one coming more than three years ago when Nicholas Henry died from stab wounds outside a nightclub in June 2012.
