Hundreds of video clips of possible law-breakers on Norfolk's roads have been sent to police by drivers, cyclists and even horse riders in the last year.

Almost 500 dashcam or headcam videos have been submitted since a reporting form was put on the police website, enabling people to upload the footage.

The clips show scores of examples of dangerous driving, including drivers not giving cyclists enough room.

Today police are appealing for more people to send in their videos as they seek to maximise the new source of evidence.

As part of that, they have released a number of videos that were sent in, including a man watching a football game on his phone while he is driving and another driver captured talking on his phone on the A11.

A police spokesman said: 'With more motorists using dashcams, mobile phones being used to capture drivers committing offences, and increasing numbers of cyclists/horse riders wearing helmet cams, there are more people than ever capturing evidence of people committing traffic offences.

'We have developed a form on our website which makes it easy to submit your footage. Since the launch of this form we have had almost 500 submissions, 40 of which relating to close-pass issues where motorist have driven too close to cyclists.

'All we ask is that if you submit your footage, you are happy to give a statement and be prepared to attend court. More details about safe use of dashcams and the process can be found on our website - www.norfolk.police.uk.'

Figures released by police showed that in June last year dashcam footage supplied by members of the public resulted in 33 prosecutions for motoring offences and 15 warning letters being issued.

There were also eight further cases that were sent to local policing teams for words of advice to be issued.

Speaking at the time, Chief Insp Kris Barnard, head of the Norfolk and Suffolk Roads Policing and Firearms Operations Unit, said: 'We are doing everything within our power to stop offenders and hopefully prevent serious or fatal collisions.

However, with the help of the public, submitting footage and supporting our investigations, we will be able to hold more lawbreakers to account.'
