The DNA gun that can invisibly tag criminals for weeks after a riot - 


British firm behind the gun in talks with several UK police forces
DNA pellets can tag clothes and penetrate through to skin - staying there for weeks
Allows police can tag troublemakers during riots 
Officers can then use the trace to place suspects at the scene of a crime using UV readers or sniffer dogs to find those tagged

It may look more like a high tech water pistol or something out of a sci-fi film than the latest weapon in the fight against crime.
But an innovative new tagging system using a gun and DNA pellets could make it easier for police to mark the cards of even the most volatile criminal.
Unlike a taser or gun that fires real bullets, the weapon won't hurt a suspect or render them incapacitated so that officers can pounce.

Instead, it will enable police to stay at a safe distance during trouble and identify criminals and arrest criminals days or even weeks after an incident. 
The High Velocity DNA Tagging System, designed for use by police forces and the military by Kent-based firm Selectamark, fires small soft green pellets containing the transparent material at a target from as far away as 40 metres.
Each pellet, which weighs less than a gram and is effectively like a paintball, contains a unique DNA code which could remain on the target for weeks.
