The accusation you raise is a key part of the interview with Melzer.
The original witness statement was intentionally destroyed, and the supervisor of the policewoman who conducted the questioning wrote an email telling her to rewrite the statement.
(The original copies of the mail exchanges between the Swedish police are actually displayed in the article.)
The statement that forms the basis of that claim "was edited without the involvement of the woman in question and it wasn’t signed by her. It is a manipulated piece of evidence out of which the Swedish authorities then constructed a story of rape."
As to your attempted lazy smearing – it doesn't really do you any favours here.
As a final plea, perhaps read-up on the details so you can get a better understanding of the case:

If indeed this evidence was all fabricated (I doubt it, but who knows), then the best venue for evaluating that claim would have been a Swedish court.
Now we will never really know exactly how strong the case was. But it was strong enough to justify bringing Assange to trial, and he has done himself no favours by hiding in an embassy for seven years.
It's always surprising to see just how grubby Assange's defenders are willing to get, up to and including rape apologism.
