A man stabbed to death in a Norwich street had acted as a peacemaker in an attempt to diffuse an argument, it emerged last night as his widow spoke about her loss for the first time.

Police have been granted extra time to interview David Stubbs, 52, of Harris Mews, Bowthorpe, at Bethel Street police station following the double stabbing which happened outside his house following an argument over a bonfire.

Jim Cushing, 37, a delivery driver and avid Norwich City fan who sold programmes outside Carrow Road's Jarrold stand at every home match, died after being stabbed in the back at about 5pm on Wednesday.

Former Bowthorpe High pupil Mr Cushing, whose home is opposite Mr Stubbs', has a young son and his wife Kim described him as a devoted father.

The attack happened after repeated complaints by neighbours about a series of bonfires lit by Mr Stubbs. Some were so concerned they had contacted police long before the stabbing to ask if the fires could be stopped.

Ian Burgess, 36, who was stabbed in the arm during the incident, had been involved in the confrontation. Mr Cushing, known locally as 'gentle Jim' had attempted to calm the situation.

Mrs Cushing, who would have celebrated her sixth wedding anniversary with Jim next month, told the EDP: "Jim was very kind and caring, a real family man. He was mine and my son's life.

"He really was a brilliant daddy and our son is a real daddy's boy. Jim was his rock and we will miss him terribly."

Following the stabbing, Mr Cushing collapsed in nearby Stylman Road and friends and family could only look on helpless as paramedics tried desperately to save his life at the scene.

Mr Burgess, of nearby Yaxley Way, was recovering at home yesterday after being discharged from the Norfolk and Norwich University Hospital and said he still felt "shaken".

High visibility patrols were underway as murder squad detectives moved to reassure residents. Forensic detectives continued to examine the scene and officers conducted door to door inquiries. A mobile police office was in the street until 6pm and will return today to allow potential witnesses to come forward and help residents seek reassurance.

Det Chf Insp Jes Fry said: "An investigation team has been established and we are currently making a large number of enquiries in relation to this incident.

"Clearly Mr Cushing's death has been a complete tragedy for his family and the incident has caused widespread concern among local people.

"I would like to reassure members of the public that a detailed and robust investigation is underway and we have made an early arrest."

Mr Stubbs lived alone in his bungalow but has an estranged wife and three children, who are now all adults.
