Sainsbury's halts facial recognition after second wrongful shoplifter flag

Sainsbury's suspended AI facial recognition at its East Dulwich store after wrongly flagging customer Matt Arnold (46) as a shoplifter and ejecting him. The company blamed human error, not the Facewatch system. A similar false ID occurred at another branch in September 2025. Comparable errors have surfaced at Home Bargains and B&M, raising broader questions about the technology's reliability.
