There's been so much misinformation in this case that it's apalling. The actual case file can be obtained here: http://www.magasinetparagraf.se/bilden/forundersokningen-avs...

Note that it is (naturally) in Swedish, however I will translate the actual allegation (under the title 'Övergreppet') here below, english is not my native tongue so if anyone else who knows swedish have any remarks on the translation, be kind to let me know:

Sexual Assault

They were sitting in bed talking and he took off her clothes. They had sex again and she realised that he had only put the condom over the tip of his penis, but she let it pass.

They went to sleep and she awoke with the sensation of him entering her. She immediately asked 'Are you wearing anything?' and he replied 'You'.

She told him 'You better not have HIV' and he replied 'Of course not'. She felt it was too late, he was already in her so she let him continue, she was too tired to tell him once more, she had been nagging him about using a condom all night.

She never had unprotected sex before. He said he wanted to come inside her, he did not say when he would but he did. A lot leaked out of her afterwards.

She told him 'What if I get pregnant?'. He answered that Sweden is a good place to have kids. She jokingly told him that if she became pregnant he would have to pay her student loans.

On the train to Enköping he had told her that he had slept in Anna Ardins bed after a party. She asked if he had sex with Anna but he said Anna liked girls, that she was a lesbian.

Now she knows that he did the same thing with Anna. She asked him about how many he has had sex with, he responded that he didn't keep count. He said that he had HIV tested himself 3 months earlier and that he had sex with a woman after that and that she was tested and not positive.

She said sarcastic things to him in a joking tone, she believes that she was trying to de-dramatize what had happened, he in turn did not seem to care. When he was told the size of her student loans he said that if he was to pay her loans then she would have to give birth to a baby.

They joked that the child would be named Afghanistan. He also said that he ought to keep abortion-pills with him that would in reality be sugar-pills.

His phone rang and he had a meeting with Aftonbladet (swedish newspaper) on tuesday at 12. She explained that he would not make it to that meeting, so he pushed his whole schedule ahead by one hour.

After that he rode a bicycle with her on the back down to the train station. She paid his ticket to Stockholm. Before they separated he told her to keep her phone on. She asked if he was going to call and he said he would.

She took the bike home, showered and changed sheets. Since she didn't make it in time for work she called in sick and stayed home. She wanted to clean up and wash everything. There was semen on the sheets and she thought it was disgusting. She also went by the drugstore and bought 'dagenefterpiller' (abortion pills).

After she had discussed with her friends she realized that she had been the victim of a crime. She went to Danderyd hospital and from there to Södersjukhuset (another hospital). There she was examined and also tested using a so called 'rape-kit'.
