RESIDENTS in Billy Row, near Crook, have had their valuable possessions marked with new security DNA.

Smartwater is already being used in Bishop Auckland, Coundon, Leeholme and St Helen Auckland by police.

The product is a liquid that acts like a chemical DNA and lasts for the lifetime of the item which has been marked.

Bishop Auckland police and Neighbourhood Watch visited Billy Row last week to mark property free of charge as part of a security drive.
