Quick Summary

The British Transport Police (BTP) conducted a facial recognition trial in London from February to July at a cost of over £320,000. During this period, more than half a million faces were scanned, but no arrests resulted directly from the technology. Despite extending the trial for four additional months with expanded deployments on London Underground stations, there was only one incorrect identification and three positive alerts related to individuals complying with court orders. Critics argue that the technology's effectiveness depends heavily on accurate watchlists and caution about its privacy implications.

Story summary

A six-month trial of live facial recognition (LFR) technology by the British Transport Police (BTP) at London railway stations ended with one false positive match and no arrests, despite scanning over 500,000 faces. The trial, which cost taxpayers more than £320,786, aimed to help catch offenders and individuals breaching court orders by identifying people on police watchlists at key transport hubs. Despite its high costs and significant deployment time involving almost 100 hours of police officers' work, the technology produced only one false alert during its February to July period in 2026. The BTP has since extended the trial for an additional four months and expanded it to include London Underground stations, prompting debates about the effectiveness and privacy implications of such surveillance technologies.

Narrative

They added: “Officers have made a number of associated arrests, including for assault, theft, possession of an offensive weapon, breach of a criminal behaviour order and public order offences, as well as locating individuals wanted by the courts and other police forces. As these arrests did not result directly from an LFR alert, they are not included within LFR performance data.
