Mr Assange is accused by Swedish authorities of one count of unlawful
coercion, two counts of sexual molestation and one count of rape earlier
In August, Mr Assange was the key speaker at a seminar on "war and the role of the media" in Stockholm, and met "Sarah", Britain's Daily Mail reports.
Mr Assange stayed at the apartment of the well-known feminist (who can't be named for legal reasons) and during his stay the two had sexual intercourse. It is not disputed by either of them that the condom broke, which is a key aspect of the case, The Australian reports.
Sarah has told Swedish tabloid Aftonbladet that Jessica "wanted to
report rape. I gave my story as testimony to her story and to support her".
"In both cases what started out as voluntary sex subsequently developed into an assault," she told the paper.
Based on the allegations of a sabotaged condom in one case and a refusal to wear one in the other, the female interviewing officer believed that Jessica had been raped and Sarah had been sexually molested.
On August 31, Stockholm police interviewed Mr Assange. The rape charge was later dropped but the case was taken over and the investigation reopened by Marianne Ny, the Director of Prosecutions in Sweden.
Ms Ny oversees the prosecution of sex crimes in Sweden and has long been
involved in cases regarding sexual abuse and violence. She denies accusations
that the case is politically motivated.
"I want to make it clear that I have not been put under any kind of pressure, political or otherwise," she said.
"The criminal investigation [into Mr Assange] has nothing to do with WikiLeaks. It concerns him personally."
However, there are reports that one of Mr Assange's accusers worked with a group that has connections to the CIA.
According to US website the Raw Story, the woman may have had "ties to the US-financed anti-Castro and anti-communist groups".
It is reported that the group is led by Carlos Alberto Montaner, who is allegedly linked to the CIA.
Mr Assange denies the charges and is fighting attempts to extradite him to Sweden. His British lawyer, Mark Stephens, says the charges stem from a "dispute over consensual but unprotected sex".
