Sainsbury's Staff Eject Wrong Shopper After Facial Recognition Alert – Again
The retailer said the mistake was caused by human error, and Facewatch says its system has a 99.98% accuracy rate.
- Sainsbury's has suspended its live facial recognition scanning technology at the East Dulwich branch after comedy promoter Matt Arnold, 46, was wrongly flagged as a shoplifter and forced to leave.
- On August 6, management stopped Arnold at a self-service till, telling him the AI system had identified him in connection with an incident 'earlier in the week.' Sainsbury's later attributed the ejection to 'human error' rather than software failure.
- Facewatch maintains a 99.98% accuracy rate with manager review required for each alert, though Arnold argued that a 0.2% error rate still affects 'a lot of people when millions go into a Sainsbury's shop each week.'
- Big Brother Watch director Silkie Carlo called for Sainsbury's to scrap the technology, warning it is 'treating customers like criminals,' despite the retailer's plans to expand facial recognition to more than 200 stores by the end of 2026.
- Another wrongful ejection occurred at Sainsbury's Elephant and Castle branch, where Warren Rajah, 42, was misidentified by the same software, while the retailer defends the rollout citing British Retail Consortium figures showing 1,600 daily incidents of violence against shopworkers.
