Cutting-edge device being built by scientists could help fight crime

Scientists have created an infrared body-scanner to help tackle surging violent crime rates. It combines a standard camera with infra-red technology to detect concealed blades from up to 20ft (6 metres) away and works through heavy clothing and even belts. The potentially life-saving technology's developers in the UK say it could one day be fitted to handheld cameras and even mobile phones. If it proves to be a viable option to law enforcement, it may be expanded to include other'geometrically similar' objects with a similar heat signature, such as stowed handguns. A proof of concept is expected in six months and if it is successful, has the potential to be implemented across the UK and around the world.
