Internet mogul Kim Dotcom "created and facilitated the distribution of stolen property", the senior FBI officer spearheading the investigation into his former file sharing site Megaupload alleges.
Dotcom has been at the centre of an extradition battle to the United States over accusations his now defunct cloud storage website allowed movie and music piracy on a global scale.
He has always denied the allegations, saying he was not responsible for the files people shared through his site.
Now the former head of the investigation into Megaupload has spoken about the allegations against Dotcom.
"Megaupload knowingly created and facilitated the distribution of stolen property," Shawn Henry, former FBI executive assistant director, told US TV's 60 Minutes programme.
