Lie detectors target benefit claim cheats
Benefit claimants and job seekers could be forced to take lie detector tests as early as next year after an early review of a pilot scheme exposed 126 benefit cheats in just three months, saving one local authority £110,000.
Last May, the Department for Work and Pensions asked Harrow council in London to undertake a year-long, £63,000 pilot of the ground-breaking Voice Risk Analysis (VRA) technology.
'We will wait until the end of the formal evaluation period to make a final decision about rolling the technology out across the country but this early review by the council is very positive,' said a spokesman for the DWP.
