Megaupload.com founder Kim Dotcom, who faces extradition to the US, has been has been denied bail by a New Zealand court.
Dotcom, a dual citizen of Germany and Finland who changed his name from Schmitz, was detained at the request of US authorities on charges of copyright infringement conspiracy.
New Zealand police also arrested a Dutch citizen who lives in New Zealand and two German nationals. Dutch police have arrested a fifth suspect, according to the BBC.
The arrests came after Federal Bureau of Investigation agents raided and shut down the Megaupload file-sharing site.
New Zealand Judge David McNaughton said Dotcom posed a flight risk and remanded him in custody until 22 February, when the US authorities' application for Dotcom's extradition will be heard.
Dotcom is wanted in the US on charges that his file-sharing website, which enabled the exchange of pirated films and music, is part of a $175m five-year copyright infringement conspiracy.
Megaupload’s founder was charged in the US because some of the site’s servers were based in Virginia and Washington, according to the US Justice Department.
If found guilty, Dotcom faces up to 20 years in prison.
