Get exclusive access to a police knife search on the ground in Worcestershire. West Mercia Police are part of a national effort to get more knives off the street.

It includes talks in schools, visits to retailers who sell knives, and 'knife sweeps' - where police scour bushes to see if any weapons turn up.

Tom Edwards reports.

The force have also been placing special 'surrender bins' at stations across the two counties, where people can dispose of a knife safely.
