When Assange arrived in Stockholm on August 11, Ardin invited him to stay at her flat while she visited her family for a few days out in the country. Ardin returned home on August 13; she and Assange had sex that night. Both have admitted a condom was used and it broke. On August 20, Ardin would go to police alleging that Assange deliberately broke the condom during sex.

Ardin's co-accuser, 26-year-old Sofia Wilen, an aspiring photographer, had sex with Assange on the evening of August 16 and again the following morning. The first time, a condom was used; the second time, there was no condom. On August 20, Wilen would go to police alleging that Assange had refused to wear a condom.
