UK man arrested in Spain, charged in US with Twitter hack

Joseph O'Connor, 22, was arrested in the coastal resort town of Estepona, Spain, on an arrest warrant accusing him of involvement in a July 2020 hack of more than 130 accounts, and of hacks that prosecutors said took over user accounts on the TikTok and Snapchat apps. Prosecutors also accuse O'Connor of cyberstalking a juvenile.

A criminal complaint filed in federal court in the Northern District of California charges O'Connor with crimes including cyberstalking, making extortive and threatening communications and intentionally accessing a computer without authorisation.

It was not immediately clear if O'Connor had a lawyer, although in prior interviews he has denied wrongdoing.

During the high-profile security breach a year ago, fake tweets were sent from the accounts of Barack Obama, Joe Biden, Mike Bloomberg and a number of tech billionaires including Amazon's then-CEO Jeff Bezos, Microsoft co-founder Bill Gates and Tesla CEO Elon Musk.

A Florida teenager was sentenced in March to three years in prison for his role in the hacking operation. Graham Ivan Clark pleaded guilty to multiple fraud charges as part of a deal with Hillsborough County prosecutors.

Andrew Warren, the Florida state attorney who prosecuted Clark, told the AP last year he considered him the mastermind of the plot.
