More than 100,000 people have had their faces scanned by police in Norwich city centre - yet just one offender has been caught. Earlier this year, officers deployed Live Facial Recognition (LFR) cameras over two days, using the high-tech equipment to identify wanted suspects and those who had failed to attend court. In just eight and a half hours of operation in March, the system scanned 101,511 passers-by. Despite the scale of the surveillance, the technology generated only two positive alerts, both leading to police interventions, according to Norfolk Constabulary data.

He was spoken to by officers who established he was not in breach of any conditions, so no further action was taken. LFR enables police to compare faces captured on a live camera feed to people on a predetermined watchlist. The technology involves using a marked van in a recognition zone the police say will be clearly signposted. It relies on biometric data which is taken by mapping out faces within the recognition zone and taking measurements of facial features, which are then compared against the police's watchlist. The data also revealed the results of the use of LFR in Great Yarmouth in May. Across two deployments, 23,883 faces were scanned, three alerts prompted interventions and four arrests were made in the seaside town. However, two of these were not linked to the LFR alerts. Despite wider public concern about misidentification, in both
