I thought there was a lot of basis for this. Testimonials from the girls in question, where the escalation to "rape" from "broken condom" was after learning about there being another girl. The definition of what can end up being translated as "rape", is also not the same as one typically assumes when hearing that word in English. "Tampering with a condom, such that it leads to unprotected sex", can be considered "rape". Yet, the act can still be consentual. The other I believe accused him of taking advantage while asleep. Which would be fair to say, not lost in translation. But, she also didn't mind him staying at her place for more days.

It's been a while, so the details might be off here. Something along those lines at least. Also, naming the accused, was awfully strange, as it is just not done in Sweden for cases like this.

Probably enough information here:
