A murder investigation has been launched after a man was fatally stabbed at the home of former world boxing champion Herbie Hide.
Police were called to the house party in Norwich just after midnight on Sunday, where they found a man in his 20s suffering from stab wounds.
According to witnesses, the victim was stabbed three times in the heart after an altercation with another guest.
Emergency services pronounced him dead at the scene.
Detective Superintendent Julian Gregory, from the joint Norfolk and Suffolk Major Investigation Team, said: "We are in the early stages of our investigation and working to establish the sequence of events which led to this man's death.
"We know this attack happened in front of many people and it is only a matter of time before we trace the offender."
Hide, who was not present when the incident occurred, won the WBO heavyweight championship in 1994.
