The mother of "gentle" Jim Cushing - stabbed to death after he tried to calm a row in a Norwich street - yesterday spoke of the huge gap his loss would leave in the lives of friends and family.

As floral tributes grew near the spot where paramedics fought to save the 37-year-old father-of-one's life, his mother Ruth told of her despair at losing a son with "a heart of gold".

The delivery driver and avid Norwich City fan was stabbed near his home in Harris Mews, Bowthorpe, after a row broke out between neighbours over a bonfire.

It is understood there had been a series of fires throughout the day which had filled the street with thick smoke. Some residents had become so concerned that they had contacted the police even before the stabbing happened.

Mr Cushing, who had lived in the area for eight years, had arrived at the scene in an attempt to diffuse the argument. Another man, Ian Burgess, 36, was stabbed in the arm after a verbal confrontation.

Earlier Mr Cushing's wife Kim had told the EDP how he had been a "brilliant daddy" to their son.

"He was very kind and caring, a real family man," she said.

Ruth Cushing said: "James had a heart of gold and was a kind, hard-working, loving, family man. He was selfless and always willing to lend a helping hand. His tragic death will leave a large gap in the lives of our family and friends."

Her sentiments were echoed by notes on floral tributes. One tribute to the former Bowthorpe High pupil read "Why does it always happen to the best" and another said "You were taken so suddenly in a world that's so unfair. We will miss your great sense of humour, your smiley face and your big generous heart".

Murder squad detectives are continuing to question 52-year-old David Stubbs who was arrested immediately after the incident.

Mr Stubbs lived alone in his bungalow. He and Mr Cushing were neighbours.
