London: Outside supermarkets or in festival crowds, millions are now having their features scanned by real-time facial-recognition systems in the UK -- the only European country to deploy the technology on a large scale.

At London's Notting Hill Carnival, where two million people are expected to celebrate Afro-Caribbean culture over Sunday and Monday, facial-recognition cameras are being deployed near entrances and exits.

The police said their objective was to identify and intercept wanted individuals by scanning faces in large crowds and comparing them with thousands of suspects already in the police database.

The technology is "an effective policing tool which has already been successfully used to locate offenders at crime hotspots resulting in well over 1,000 arrests since the start of 2024," said Metropolitan Police chief Mark Rowley.

The technology was first tested in 2016 and its use has increased considerably over the past three years in the United Kingdom.
