HUNDREDS of suspects have been screened in custody as part of a operation launched by Cheshire Police to target those who commit a crime.

A total of 433 people, who have passed through Cheshire Police’s custody suites, have undergone an examination to see if they can be forensically linked to a crime scene.

Operation Shield, which is a forensic property marking initiative, uses a DNA system is unique to each address and helps to identify stolen items if they are recovered.

How does it work?
Operation Shield works by using state-of-the-art unique DNA liquid which contains an individual code to mark property in your home, garage and shed. The DNA coding in the liquid is registered solely to your address and added to a database, meaning that if anything is ever stolen it can be traced back to you.

The liquid is barely visible and is hard for offenders to see. Once it’s applied to property it is extremely difficult to remove, meaning that if an offender is ever caught in possession of stolen items they can be linked directly back to the crime scene.

All property recovered by Cheshire Police is scanned by Ultra-Violet beams under Operation Shield to check for traces of unique DNA liquid. If we detect any evidence of the liquid, the property is then closely examined with high-power microscopes which can identify the individual code. This information is then input into the database of registered addresses and items can be traced back to the owner.

Homeowners can get marking kits which come with a container of the unique liquid, an application brush and details of how to register property. Once property has been marked and registered, stickers can be displayed around your property to work as a deterrent to any burglars who may be looking to target your home.

Assistant chief constable Mark Roberts said: “All tests in custody for the traceable liquid have resulted in a negative result up to now − reinforcing the message that Operation Shield is making its mark across the county.

“The aim of the operation is to deter would-be thieves and burglars − and provide reassurance for local residents.”
