A former National Crime Agency employee has 'destroyed his good life and career' after being jailed for stealing 50 Bitcoin from a dark web drug dealer, a prosecutor has told an exclusive Mail podcast.

Paul Chowles, 42, was sentenced to five and a half years in prison for stealing Bitcoin now worth £4.4 million from a drug dealer who was under investigation in 2017.

Drug dealer Thomas White, who operated a dark web marketplace known as 'Silk Road 2.0' from his Liverpool home, alerted police to Chowles after telling investigators that proceeds from his criminal enterprise had gone missing.

Chowles's theft went undetected for five years as he used his expertise in cybercrime to conceal his ill-gotten gains.

Speaking to the Mail's Trial Plus podcast, specialist prosecutor Alex Johnson, who worked for the Crown Prosecution Service against Chowles, described why the case is truly 'a first of its kind.'
