The former wife of cricketer Imran Khan was among those who put up a total of £240,000 (Rs 2.13 crore) bail for the WikiLeaks founder.
Assange’s supporters risk losing their money after he spent two nights in the embassy in Knightsbridge, central London.
But while some have likened him to Chinese dissidents and praised his attempt to claim political asylum from Ecuador, Khan said his alleged victims deserved justice too and that he should respond to the allegations.
Writing on Twitter, she said: “For the record, in response to those asking about Assange & bail money... I personally would like to see Assange confront the rape allegations in Sweden and the two women at the centre have a right to a response.”
She also highlighted Assange’s concerns that because his whistle-blowing website published sensitive US diplomatic cables and military files, he faces further extradition to America.
She wrote: “But there is no doubt that Assange has a real fear of being extradited to the US nor that the US gov is out to get WikiLeaks.”
