Their chance to pursue charges in the case will expire next summer, under Sweden's statute of limitations.
Rape charges: Swedish prosecutors filed preliminary charges - a step short of formal charges - after Assange's visit to the Scandanavian country in 2010.
After Assange skipped bail in the United Kingdom and went into hiding at the Ecuadorian embassy in London, "the extradition order was impossible to enforce", Persson added. He was dramatically arrested by British police in April after being thrown out of the Ecuadorean Embassy. Sweden dropped the investigation six months later, in May 2017.
"To be able to execute a detention order, the prosecutor will issue a European Arrest Warrant".
People hold signs during a protest outside Southwark Crown Court where WikiLeaks founder Julian Assange will be sentenced, in London, Britain, May 1, 2019. Assange enters Ecuadorian embassy in central London, seeking asylum on June 19.
"However, in my view the Swedish case can proceed concurrently with the proceedings in the UK". He is also being held on a U.S. extradition warrant for allegedly hacking into a Pentagon computer. The prosecutor stated that London would decide which country's request will have priority.
Sweden will seek to have Julian Assange extradited from the United Kingdom, a chief prosecutor said on Monday.
Assange had also faced investigation for a second sex-related allegation in Sweden, which was dropped in 2017 because the statute of limitations had expired.
Assange's Swedish lawyer, Per Samuelsson, told The New York Times that Sweden's decision is "not proportionate", saying, "He has been sentenced to 50 weeks. This was not the case prior to April 11".
"How that will happen now, I don't know".
Assange's supporters cast him as a dissident facing the wrath of a superpower over one of the largest compromises of classified information in USA history.
The assault allegations relate to complaints made by two Swedish women who said they were the victims of sex crimes committed by Mr Assange in 2010. However, Hrafnsson slammed the political aspect, which, as he states, has always been associated with the criminal case.
Following the announcement, WikiLeaks said the investigation would give Assange a chance to clear his name. Such calls serve to displace the critical issue of Assange's impending U.S. extradition over WikiLeaks publications (whether from United Kingdom or Sweden).
Assange, 47, has previously spoken to Swedish authorities about the sexual allegations against him; Persson says new questioning is needed.
"My client feels great gratitude and she is very hopeful about getting restitution and we both hope that justice will win".
The lawyer also called on the prosecution to make haste, as the statute of limitations deadline is approaching and it could take time to have Assange extradited to Sweden. The Swedish prosecution questioned Assange on two separate occasions, in 2010 and 2016.
