Facial recognition technology lead to no arrests in one Suffolk town. The system processed 51,833 faces in Bury St Edmunds and checked them against a watch list containing 793 people. Suffolk Constabulary used the technology in the town centre on August 26 as part of a three-day operation across the county. The force says live facial recognition is used to help locate people wanted in connection with serious offences. The technology compares live camera feeds with images on a predetermined watch list.

People who are not on the watch list cannot be matched, and their biometric data is automatically deleted. A Suffolk Constabulary spokesman said: “This innovative technology can play a vital role in protecting people, keeping them safe, investigating crimes, and getting justice for victims. It also means we are saving time and effort for our officers, leaving them able to do other work to protect and help the public. “It was also very encouraging to see the public expressing curiosity and approaching us in Ipswich to learn and understand more about the technology.” In Ipswich, two arrests were made, after 30,000 faces were scanned.
