Scotland Yard uses lie detector tests on terror informants

Scotland Yard has started using lie detector tests on terror informants to ensure the quality of the intelligence is strong, according to a media report. The Metropolitan Police s counter-terrorism command have launched a top-secret scheme to get their sources undertake polygraph examinations in an attempt to weed out lies and misinformation, 'The Sunday Times' reports.

The programme, which is believed to be unprecedented in British policing, is an attempt to verify intelligence from people who are often of questionable integrity as they themselves operate in the criminal underworld. "We are not prepared to discuss this," Scotland Yard said in reference to the scheme.
