Police facial recognition arrests

London police began a real‑time facial‑recognition pilot at Sloane Square in 2024, reporting roughly 2,500 detentions by mid‑2026, including about 900 that year. Officials praised the system’s effectiveness, while privacy advocates warned of invasions of civil liberties in the absence of regulation.

In the weeks that followed, Essex Police revived their own live facial‑recognition deployment after an Information Commissioner’s Office audit, scanning 353,000 faces across 22 operations and making 57 arrests with a very low false‑positive rate. Simultaneously, Delhi police introduced mobile vans equipped with AI‑enabled cameras to monitor student protests, prompting legal challenges and criticism over mass surveillance and constitutional rights.

The two reports illustrate how police forces in the UK are expanding live facial‑recognition use despite ongoing public debate, while the technology is also being adopted abroad, where it faces heightened legal and privacy scrutiny.
