"He is the biggest copyright infringer in the world," Suh said to the AP.
Megaupload's lawyer, Ira Rothken, said the claims are without merit and will be fought vigorously.
He called the case an unwarranted show of force by authorities desperate to prove they are serious about battling copyright fraud. If federal authorities had a problem with Megaupload, Rothken said, they should have sued first in civil court rather than having people thrown in jail.
Dotcom now faces a series of charges in the U.S., including copyright fraud and money laundering. The racketeering charges alone carry a maximum sentence of 20 years.
In New Zealand last month, 10 years after threatening to kill himself on his 28th birthday, Dotcom planned a big celebration for his 38th. After all, those youthful fantasies of wealth and notoriety had come true.
But police were ready. On Jan. 20, the day before his birthday, they swooped down in helicopters onto the grounds of his mansion and cut their way into a safe room where they found Dotcom hiding. They also arrested three of his colleagues.
The party is on hold.
