An eye test that can tell police if you’re lying has been developed by scientists.
The technology tracks the movement of your eyeballs.
Experiments showed even seasoned liars couldn’t hide their reactions.
It could help police crack terrorist cells, according to the research.
Study leader Dr Ailsa Millen, a psychologist at the University of Stirling in Scotland, said: ‘Criminal networks, such as terrorist groups, might deny knowledge to protect one another or a victim might be too afraid to identify their attacker.
‘Our study tracked people’s eye movements when they denied knowledge of someone they knew.
‘Instead of looking for signs of lying directly, we looked for markers of recognition in patterns of eye fixations, such as how individuals looked at a photograph of someone they recognised, compared to someone they did not.
‘The aim was to determine if liars could conceal recognition by following instructions to look at every familiar and unfamiliar face with the same sequence of eye fixations – they could not.’
