A prolific sex offender who spent 27 years on the run has finally been caught - thanks to the use of artificial intelligence (AI).

Richard Burrows stole an innocent man’s identity when he vanished after systematically abusing 24 young boys. He even featured on the BBC's Crimewatch which showed the digital updating of his photograph to highlight how he could look as an old man. No trace was found - until a simple piece of desktop research provided a breakthrough. Officers at Cheshire Police ran the manipulated mugshot through facial recognition program Pimeyes.
