While all investigative steps have been taken in the case, including additional interviews with Assange, the evidence does not prove he committed a criminal act according to the prosecutor.
The Prosecution Authority added that oral testimony in the case had “weakened,” which is natural over time.
Sweden had previously dropped the case against Assange in May of 2017, announcing that “Given that all options for moving the investigation forward are now exhausted, it appears that — in light of the views expressed by the supreme court on the proportionality of arresting someone in absentia — it is no longer proportional to maintain the decision to remand Julian Assange in his absence”
Then, after two years prosecutors revived their inquiry into Assange following his ouster from the embassy. At the time, Wikileaks editor-in-chief Kristinn Hrafnsson accused Sweden of bowing to external pressure, saying “there has been considerable political pressure on Sweden to reopen their investigation, but there has always been political pressure surrounding this case.”
Assange has avoided extradition to Sweden for seven years after he sought refuge at the Ecuadorian embassy in London in 2012. The 48-year-old publisher was kicked out in May and was sentenced to 50 weeks in jail for breaching his bail conditions. He is currently being held at Belmarsh prison in London.
The decision can be appealed.
