WELLINGTON, New Zealand (AP) — Kim Dotcom, the internet entrepreneur fighting deportation from New Zealand to the United States on charges relating to his file-sharing website Megaupload, has suffered a “serious stroke”, a post on his X account said Monday.

“I have the best health professionals helping me to make a recovery. I will be back as soon as I can. Please be patient and pray for my family and I,” the post said.

Dotcom’s lawyer, Ira Rothken, confirmed to The Associated Press that the contents of the statement were accurate. Rothken would not say whether Dotcom or someone else wrote the post and did not provide further details.

News of his ill health comes during a protracted battle by the U.S. government to extradite the Finnish-German millionaire to the United States from New Zealand to face charges of copyright infringement, money laundering and racketeering.

In August, New Zealand ’s justice minister announced that Dotcom should be surrendered to the United States to face trial, a ruling intended to cap a 12-year legal battle. A date for the extradition was not set, and Paul Goldsmith, the minister, said Dotcom would be allowed “a short period of time to consider and take advice” on the decision.

Rothken at the time wrote on X that Dotcom intended to challenge the order in court through a judicial review, in which a judge is asked to evaluate whether an official’s decision was reached correctly.

Lawyers for Dotcom and the others arrested had argued that it was the users of the site, founded in 2005, who chose to pirate material, not its founders. But prosecutors argued the men were the architects of a vast criminal enterprise, with the Department of Justice describing it as the largest criminal copyright case in U.S. history.
