London: shopper told to leave a Sainsbury's store after a Facewatch facial recognition alert, which Sainsbury's says concerned a different person
A shopper at the Sainsbury's store in Elephant and Castle, London, told PA that staff approached the shopper on 27 January, asked the shopper to leave and took the shopping. The BBC and LBC report that staff pointed to a sign about the store's Facewatch facial recognition system and told the shopper to contact Facewatch. Sainsbury's said the system had flagged a different person. Sainsbury's and Facewatch said a staff member approached the wrong customer, and Facewatch said it held no alert or record for the shopper. To confirm this, the shopper sent Facewatch a passport copy and a photo. Sainsbury's apologised, offered a 75 pound voucher and said store management would receive additional training. The shopper reports embarrassment and feeling like a criminal. Both companies attribute the error to store staff.
