A mother from Luton has hit out at a coroner's verdict on the death of her son who was stabbed to death at a birthday party in 2012.
Taffy Khan was fatally wounded at the house owned by former boxing champion Herbie Hide in Norfolk.
Today Coroner Jacqueline Lake recorded a narrative verdict rather than one of unlawful killing.
Mr Khan's mother Shereen Sinclair described that decision as outrageous.

A coroner has called for witnesses to break their silence after ruling a man killed at world champion boxer Herbie Hide's home was the victim of an "unprovoked attack".
Tafadzwa Khan, 25, known as Taffy, was found dead after the birthday party held on March 17 2012. About 200 people attended the event at Mr Hide's mansion in Long Lane, Bawburgh, Norfolk.
Norfolk Police charged party-goer Joshua Burton, who was 20 at the time, with murder but the case was later dismissed with the force blaming a culture of silence preventing crucial witnesses coming forward.
Today coroner Jacqueline Lake said she could not be certain he was the victim of an unlawful killing, instead returning a narrative conclusion that he died after being stabbed three times in an unprovoked assault.
She said: "It is clear that Mr Khan was stabbed and the assault was not in self-defence. There is no evidence that he was acting in an aggressive or provoking manner.
"I would echo the police appeal that if anybody has any information, they should come forward."
Family and friends of a man stabbed to death at former world champion boxer Herbie Hide's Norfolk home have issued a fresh plea for justice after an inquest heard his killer has never been caught.
Tafadzwa Khan, 25, known as Taffy, was found dead after a birthday party held on March 17, 2012, and attended by about 200 people at Mr Hide's mansion in Long Lane, Bawburgh, Norfolk.
Norfolk Police charged partygoer Joshua Burton, 20, with his murder but the case was later dismissed with the force saying crucial witnesses had refused to come forward.
The inquest is expected to last three days, with Mr Burton due to give evidence tomorrow.
Mr Khan was originally from Zimbabwe and was living at the YMCA centre in Norwich at the time.
Police have said they do not believe Mr Hide was at the house at the time of the death.
He won the WBO heavyweight title for the first time in 1994.
He regained the title in 1997 and made two successful defences before losing to Vitali Klitschko in 1999.
