Cameras which clip on police officers’ uniforms have been credited with helping cut crime and disorder.

The ‘Bodycams’ record evidence that can be used in court, and have been credited with increasing the number of convictions for violent crime and public order since they were brought on to the streets six months ago.

In the past year, police in Oxford have solved half of all violent crime incidents – compared to 36 per cent in 2006 and 41 per cent in 2007.

Det Chief Insp Colin Paine, head of priority crime, said: “There are a few reasons why violent crime has fallen by 25 per cent, such as licensed premises changing from glass to polycarbonates.”

The number of solved crimes has also increased, and Mr Paine said: “One of the main reasons in the city centre are the body-worn cameras which provide evidence which cannot be disputed.”

Police have eight cameras at their disposal in Oxford, with a further 30 across the Vale of White Horse, South Oxfordshire and Cherwell districts.

They have also bought 70 cameras which strap to helmets.

Officers are also using the cameras for domestic abuse incidents and when carrying out drug raids.

None of the footage is kept if no crime has been committed.

Insp Matt Bullivant, city centre inspector, said there were several cases for public order offences and violence currently going through courts where body camera footage was being used in evidence.

He said: “Body-worn cameras are a piece of kit used to fight violent crime.

“They are also a tool that can be used in everyday policing, such as major incidents and domestic violence. They will be useful for any type of crime.

“The body-worn cameras go where the CCTV cannot and act as a deterrent.

“Not only does it tackle anti-social behaviour but can have a moderating effect on people’s behaviour. It is a great crime reduction tool and very effective.

“I want them rolled out to as many officers as possible.”

The body cameras were paid for by the Home Office and Crime and Disorder Reduction Partnership.
