The Justice Department said in a statement said that Kim Dotcom, 37, and three other employees were arrested Thursday in New Zealand at the request of U.S. officials. Three other defendants are at large.

The Electronic Frontier Foundation, which defends free speech and digital rights online, said in a statement that, “This kind of application of international criminal procedures to Internet policy issues sets a terrifying precedent. If the United States can seize a Dutch citizen in New Zealand over a copyright claim, what is next?”

Before Megaupload was taken down, it posted a statement saying allegations that it facilitated massive breaches of copyright laws were “grotesquely overblown.”

“The fact is that the vast majority of Mega’s Internet traffic is legitimate, and we are here to stay. If the content industry would like to take advantage of our popularity, we are happy to enter into a dialogue. We have some good ideas. Please get in touch,” the statement said.
