Nathan Wyatt was previously arrested by UK police investigating the hacking of an iCloud account belonging to Pippa Matthews.
A British man who helped steal information from several companies as a key member of The Dark Overlord hacking group has been jailed for five years in the US.
Nathan Francis Wyatt pleaded guilty in federal court in St Louis, Missouri, to conspiring to commit aggravated identity theft and computer fraud.
Federal prosecutors said The Dark Overlord stole medical records, client files and personal information from the US companies, then demanded between $75,000 and $300,000 (£58,000-£234,000) worth of Bitcoin to return the information.
While none of the companies paid the ransom, the conspiracy cost them due to the intrusion and release of data, according to federal prosecutor Laura Kathleen Berstein.
