Dutch police have arrested an Estonian man in connection with the Megaupload case into massive online piracy, Dutch prosecutors said Tuesday.
"He was arrested on Friday at the request of the United States," said Paul van der Zanden, spokesman for the prosecutors' office.
"He appeared before a judge on Monday, who decided he should remain in custody for another 60 days," Van der Zanden told AFP.
Saying the arrest was "in connection with the Megaupload case" the Dutch spokesman declined to give further details about the Estonian, adding "the FBI is handling the case" and that the Netherlands have not yet received an extradition request from the US.
A 72-page indictment before a US court however contained the name of Andrus Nomm, which it named as a "citizen of Estonia" and Megaupload's head of Development Software Division.
Megaupload founder Kim Dotcom, 37, also known as Kim Schmitz, was set to learn Wednesday if he will remain behind bars while US authorities seek his extradition on allegations of massive copyright theft.
The Internet tycoon has been in custody since police raided his Auckland mansion last Friday but vigorously denies any wrongdoing and has applied for bail as US moves to extradite him make their way through the courts.
