Demonoid, along with Megaupload and The Pirate Bay, was listed on the US Government’s Notorious Markets List, a document highlighting services that "merit further investigation for possible intellectual property rights infringements".
Ukrainian authorities have taken down Demonoid.com, one of the world's largest torrent file-sharing sites.
The country's Ministry of Internal Affairs raided the data centre that was hosting the website's servers. Torrents allow users to download music, video and other internet content by downloading small bits of files from others' computers at the same time.
The shutdown is the latest in a gobal campaign against file sharing websites. It follows the closure of Megaupload by the Us and the EU blocking of The Pirate Bay.
