- Facewatch, a facial recognition system used by over 100 UK businesses, is launching a real-time police alert feature for known offenders.
- The new feature will alert police within an average of four seconds when a match is detected.

- Sainsbury's plans to significantly expand its use of the Facewatch system.
- Critics argue the technology is disproportionate and that less intrusive methods exist for catching shoplifters.
Facewatch, a facial recognition system utilized by over 100 UK businesses including Sainsbury’s, B&M, and Spar, is set to introduce a new feature that will alert police in real-time when serious offenders are identified. The company's CEO, Nick Fisher, stated the system will notify law enforcement within an average of four seconds upon detecting a match with individuals on its network.
This development has drawn sharp criticism from civil liberties groups, who express alarm over what they describe as a "dangerous escalation" towards pervasive surveillance and the criminalization of the retail sector. Charlie Whelton of Liberty highlighted concerns about the "untested, opaque development" and the lack of regulation governing facial recognition technology. He argued that the system could lead to individuals being targeted by police for potential crimes rather than actual offenses, and noted the technology's fallibility, which can result in false identifications.
Reports indicate that individuals, particularly from Black and Asian communities, are more likely to be misidentified by Facewatch technology. Critics have described the experience as "Orwellian" and feeling "guilty until proven innocent." Britain's biometrics watchdogs have also cautioned that oversight of facial recognition is lagging behind its rapid expansion. Sarah Lasoye from Open Rights Group stated that the technology "entrenches a climate of surveillance" and infringes on people's rights, potentially leading to immediate police encounters during everyday shopping.
Sainsbury's has announced plans to increase its use of Facewatch from 55 to over 200 stores by the end of the year. Facewatch reported nearly 300,000 alerts for known repeat offenders in the first six months of 2026, claiming its system helps staff intervene before incidents occur. However, experts like Nuala Polo from the Ada Lovelace Institute argue that less intrusive methods are available for catching shoplifters. Concerns also exist regarding the discrepancy between planned regulation for police use and the unchecked use of the technology in the private sector, potentially creating "backdoors" with lower standards.
Big Brother Watch criticized police for engaging with what they termed a "cowboy operation," noting that individuals could be matched against "secret blacklists compiled by unaccountable businesses and private security guards."
