A man has been arrested following the death of a pedestrian after an alleged argument with a cyclist in Norwich.

William Phillips, 34, from Derby Street, Norwich, died after he was involved in an incident near to the doctor's surgery in Oak Street, off St Crispins Road.

Mr Phillips, who was wearing a cream top, light coloured jeans and desert boots fell to floor during the incident, which happened at about 8.50am on Wednesday, July 18.

Mr Phillips received initial treatment at the surgery, and was taken to the Norfolk and Norwich University Hospital.

He was found dead at his home around 5pm on Friday, July 20, by his mother.

A post mortem examination has been carried out but further tests will have to be done before the cause of death is established.

A 22-year-old man from Norwich was yesterday arrested in connection with the incident and is in police custody.

Temporary Detective Superintendent Jes Fry said he was encouraged by the response to media appeals, but was still keen to hear from anyone with information about the incident.

He added: 'We're still waiting to find someone who saw what started this off – that's the key issue.'

Anyone with information should call police on 101 or call Crimestoppers on 0800 555 111.
