Fast food criminals caught by 'sticky fingers'
Criminals who eat fast foods are more likely to get caught because their fingerprints are easier to find.
A new fingerprinting technique has been developed which can identify a criminal from the corrosion their sweat leaves on metal surfaces.
The more salty their fingertip sweat - increased by eating fast foods - the more of a mark they leave.
Unlike traditional fingerprinting it does not rely on residue that can be wiped away and scientists can 'visualise fingerprints' even after the print itself has been removed.
The odd news could see burglars insisting on a organic diet in addition to a fast getaway car.
Dr John Bond, a researcher at the University of Leicester said: "On the basis that processed foods tend to be high in salt as a preservative, the body needs to excrete excess salt which comes out as sweat through the pores in our fingers.
"So the sweaty fingerprint impression you leave when you touch a surface will be high in salt if you eat a lot of processed foods -the higher the salt, the better the corrosion of the metal."
