London trial of facial recognition yields no arrests

A six-month live facial recognition trial at London railway stations scanned over 500,000 faces and cost £320,786, resulting in only one alert that proved to be a false positive, with no arrests made. The British Transport Police trial, aiming to identify people breaching court orders, has since been extended. Since the extension, three people were matched but were found to be compliant with court conditions.

• Over 500,000 faces scanned in six months
• Trial cost £320,786 with one false alert
• No arrests resulted from the initial trial
• Trial extended to more stations
• Three more alerts post-extension, all law-abiding
