A UK school dropout is fighting extradition to the US over a £400 million computer hack. Diogo Santos Coelho, 23, allegedly set up one of the world’s largest hacker forums after quitting school at 15 without sitting his GCSEs in Croydon, South London. The RaidForums website enabled criminals to buy and sell people’s personal and financial information using PayPal and cryptocurrency. Coelho moved back to his native Portugal but was arrested on January 31 last year after returning to London to visit his sick mother. The operation – involving the FBI, Europol and the National Crime Agency – also netted two alleged accomplices, including a 22-year-old in Croydon. Coelho is on £30,000 bail and an electronic curfew while living at a flat in Vauxhall, South London. He is wanted for trial in Richmond, Virginia, on charges including fraud and identity theft. Now, a UK judge has sent his case to Home Secretary Suella Braverman – who will decide whether to extradite him. If Ms Braverman decides to extradite Coelho, he can appeal. Both the Home Office and Coelho will not comment.
