The accusations of rape are done by an overzealous prosecution office that has hijacked the case later; it seems they have the right to do that. That the office chose to make the accusations augmented by descriptive statements from the two women gives the impression that the two are the accusers. Both (or at least one, supported by the other) have since requested that the issue be dropped.
To see the entire arguments of the prosecution and the defense in today's session, read the liveblog[1] by Falkvinge (now ended, of course).
