While knife crime rates in the county remain well below those of other urban forces, police want to ensure it stays that way.

New confidential knife crime reporting lines, more work in schools and improved systems to stop knives being sold to those underage are among the options.

Measures which could be introduced include:

New knife crime prevention schemes in schools;

Use of new mobile knife search arches in locations such as sporting events;

A confidential knife reporting service with CrimeStoppers;

Closer work with hospital casualty departments to get a clearer picture of knife injuries;

More stop and searches for knives in areas where assaults have taken place;

n A new knife related Responsible Retailer scheme to be developed with Trading Standards officers to stop knives being sold to those who are underage.

David Evans, West Yorkshire Police's Assistant Chief Constable for Local Policing, said knife crime in West Yorkshire, while troubling, was not as significant as in other places but the force was determined to make sure it remained low. "These measures are intended to reassure the public and ensure we do not develop a problem."

Knife crime rates in West Yorkshire have been largely static, accounting for less than one per cent of violent crime over the last few years.

Mr Evans said: "We will continue to play an active and leading role in making our county safer but we will not be successful alone. We believe that the public understand that tackling the issues of knives is not just a matter for the police; any sensible response must include the involvement of parents, schools and other partner agencies."
