Live facial recognition vans are set to return to Slough High Street next week. On Tuesday, April 21, police will attempt to "identify known suspects" and "deter crime" using CCTV vans with algorithms built to spot people on a "watchlist". The force stated: "Our Live Facial Recognition (LFR) vans will be coming to Slough High Street on Tues (21/4). "We will be working to identify known suspects, deter crime & help keep our communities safer. "Any questions? "Want to see how the technology works? "Come over & chat with our team." This will not be the first time that the cameras have been used in town. In February, Thames Valley Police (TVP) said it had launched Operation Catalyst in a bid to reduce the interrelated issues of anti-social behaviour and violent crime. The force worked with the Safer Towns Team to deploy LFR vans on the High Street and said that this resulted in the arrest of three wanted individuals while providing a 'visible deterrent'. Previously, a TVP spokesperson stated: "We always ensure the public is informed when LFR is in use through signage and social media updates and welcome questions throughout the deployments. "Once again a big thank you to everyone who stopped to speak with us this week - we're here to serve and protect our community."
