It is seen every day; the police are called to a crime scene only to see the suspects fleeing. However, getting away might not be all that easy if the police were issued with these DNA Guns, they fire a SelectaDNA High Velocity pellet that weighs just one gram and leaves a unique DNA trace that can stick around for weeks, allowing the Police to place suspects at the scene.
According to Selectamark Managing Director Andrew Knights he said;
On contact with the target the uniquely-coded SelectaDNA solution leaves a synthetic DNA trace mark that will enable the relevant authorities to confirm or eliminate that person from their involvement in a particular situation and could ultimately lead to arrest and prosecution.
There is no announcement as to if this technology will be used by UK Police Forces yet.
