A family has urged cyclists to wear helmets after paying tribute to a 21-year-old father-of-one who died early last month.

Sam Crisp died when his cycle was in collision with a white Vauxhall Corsa at about 5.15pm on Thursday, May 3, in Sprowston Road, close to the junction with Templemere in Norwich.

Witnesses to the accident have been slow in coming forward and the family plans to put posters up in shops in the area in a bid to get more information about the crash.

It emerged today that Mr Crisp was not wearing a helmet, and his mother, Patricia Crisp, was travelling in a bus behind him, which arrived at the scene just 10 minutes after the fatal crash.

Mr Crisp's parents, Patricia and Paul, were too upset to pay tribute to their son in the weeks following the tragedy, but yesterday they said the 21-year-old, who had just moved in to live with his mother in Templemere, was 'loved' by so many people.

Mrs Crisp said: 'He was just a typical 21-year-old. He loved playing snooker at Riley's in Norwich. He moaned about not having enough time to see his son Riley, who is five, because he worked a lot of overtime.

'After he died there were about 80 bouquets of flowers left at the site of the accident. Sam's brother Lee and I put new flowers up every day.'

Sam's father Paul added: 'He was loved by so many people. There were about 250 people at his funeral. He did not have a bad bone in his body. He had everything to live for and it was such a waste of a life.'

The family said Mr Crisp was not wearing a helmet, and urged other cyclists to wear them. 'We don't know if it would have saved Sam, but it might have helped,' they said.

Mr Crisp worked at John Menzies in the west of the city but was on holiday on the week of the accident, and was cycling home after meeting his mother at Anglia Square shopping centre.

Police have renewed appeals about the collision.

They said CCTV images showed a number of vehicles outside a row of shops opposite the junction with Templemere, whose occupants may have information about the collision. They are keen to speak to the driver of a red Peugeot 406 saloon which was parked between the Chip Stop and a card shop called Say it With a Card. They say the driver probably witnessed the collision. Police emphasise that the red Peugeot 406 salon had no involvement in the collision and was stationary and parked correctly at the time.

Any witnesses should contact investigating officer PC Steve Crowley at Wymondham Roads Policing Unit on 101.
