A Cardiff man has filed a formal complaint with the Information Commissioner’s Office after being wrongly accused of theft in a store using facial recognition software.
The case is now drawing wider attention to the unchecked spread of biometric surveillance in everyday retail environments.
On 29 April 2025, Byron Long, 66, arrived at the B&M outlet in Cardiff Bay Retail Park expecting an ordinary shopping trip.
Instead, he was approached by staff and told he was barred from the premises. In front of other customers, he was accused of stealing £75 ($101) worth of goods during a visit earlier that month.
That accusation was entirely false. During the visit in question on 9 April, Long had bought a single item: a £7 ($9.50) packet of cat treats. He paid for them in full. He later obtained CCTV footage showing himself at the checkout in a Red Bull Formula 1 jacket, clearly completing the purchase.
“It was a horrible experience, and I haven’t been back to the store since. The incident has had a very serious impact on my mental health, which is very fragile anyway, and I am now very anxious whenever I go shopping,” Long said, as reported by Nation Cymru.
The misidentification came from Facewatch, a private firm contracted by retailers to run facial recognition scans on customers. Images from Long’s previous visit were processed and matched to a database of alleged offenders. That match triggered the alert that led B&M staff to accuse him.
B&M later acknowledged the error, issuing a written apology and stating: “Our B&M store and security teams have a duty of care to all our customers and to our company, and this includes challenging people that they believe are potentially shoplifting. This is an extremely difficult task, and sadly we don’t always get it right; your case would be one of these instances…We can confirm your data has been removed from Facewatch.”
They also offered a £25 ($34) voucher as compensation, an offer Long flatly rejected.
Facewatch responded to the incident by suspending the user who had submitted the incorrect data. Michele Bond, the company’s Head of Incident Review and Data Protection Enquiries, said: “Facewatch Incident data is submitted by authorized users, who must confirm the accuracy of the information provided. Once the error was identified, the user responsible was immediately suspended from using the Facewatch system.”
Long has since taken the matter to Big Brother Watch, a civil liberties group focused on privacy and surveillance. The organization has now submitted a complaint to the ICO on his behalf.
