Radiohead appear to be disappearing from the Internet, with the band deleting Facebook posts, tweets and profile pictures, reports Pitchfork.

The band's Facebook page and Twitter page are now completely blank, as is the Twitter account of lead singer Thom Yorke.

Radiohead's website was also steadily deleted, until it disappeared altogether leaving just an empty white page.

Their disappearance from the Internet comes just a day after several UK fans received mysterious flyers through the post with the words "Sing a song of sixpence that goes/Burn the Witch/We know where you live."

However the significance of the flyers – and their Internet disappearance – remains unknown.
