Mother's plea over Tafadzwa Kahn death at Herbie Hide's home
The mother of a man stabbed to death at the Norwich home of former boxing world champion Herbie Hide has asked people with information to contact police.
Tafadzwa Kahn, 25, of St Giles Street, Norwich, died from a stab wound during a party at the house in Long Lane, Bawburgh, on Sunday.
His mother, Shereen Sinclair, said she had been "deeply saddened" by her son's death and touched by tributes to him.
Three people have been arrested on suspicion of murder.
Ms Sinclair said her son, who was known as Taffy, was a committed Christian who loved poetry.
She said: "I'm deeply saddened by the loss of my son and I'm touched by the many flowers and lovely tributes left outside the YMCA [where Mr Kahn had lived].
"I've been encouraged by the number of people coming forward with information, especially those from the black community, and I would urge anyone else who knows what happened or has any information to contact the police."
Two men aged 18 and 20 arrested in connection with the incident remain in police custody while a third suspect, a 16-year-old male, has been released on bail pending further inquiries.
Detectives said the stabbing followed an argument and more than 100 people were at the party at the time.
Police said earlier they were "fairly certain" Mr Hide was not on the premises at the time of the stabbing.
Mr Hide and his family are living elsewhere while investigations at the house continue.
He won the WBO (World Boxing Organisation) heavyweight title for the first time in 1994, beating American Michael Bentt, but lost it to another American, Riddick Bowe, the following year.
He regained the title in 1997 and made two successful defences before losing to Vitali Klitschko in 1999.
