The man known as Kim Dotcom, the founder of the file-sharing website Megaupload, remains in custody in New Zealand.
The 38-year-old was arrested along with three others at his mansion close to Auckland on Friday at the request of the FBI. US authorities want Dotcom extradited on charges of Internet piracy and money laundering, charges Dotcom denies.
The FBI alleges the German national, also known as Kim Schmitz, masterminded a scheme to copy and distribute music, movies and other copyrighted material without permission. It is claimed that Dotcom’s activities made the company some 135 million euros.
The judge reserved his bail decision until Wednesday, due to the “seriousness of the issues.”
The arrest comes as the movie and music industries want the US Congress to get tough on internet piracy and content theft.
As news of Dotcom’s arrest spread round the world hackers launched attacks on the public websites of the US Justice Department, Universal Music and the two trade groups that represent the film and music industries.
