Internet tycoon Kim Dotcom has claimed US officials were among the biggest users of his Megaupload website before it was shut down for alleged copyright infringement.
Dotcom, who founded Megaupload, is on bail at his Coatesville mansion ahead of a hearing to decide whether he will be extradited to the US to face charges.
The 38-year-old and his associates, Mathias Ortmann, Bran van der Kolk and Finn Batato, are accused of breaching international copyright laws to the value of US$500 million.
Megaupload was shut down in January, soon after the four were arrested.
Website TorrentFreak reports Dotcom is taking legal action in an attempt to "reunite" former Megaupload users with data they download from the site.
