The Prime Minister Ulf Kristersson (M) has referred to silent diplomacy and also to help from European colleagues.
It seems that some kind of conversation has taken place where Turkey has got something they want or that Sweden has put pressure on Turkey and clarified how important it is for Sweden that Joakim is sent back and that it has yielded results. And that other European countries have put pressure, says Levin, who is the head of the institute for Turkey studies at Stockholm University.
In such contexts, it may be both sticks and carrots that are being used.
Levin means that it has gone quickly to get Medin free.
I expected him to be released after a few months, maybe up to a year.
Important signal
The Turkish accusations of terrorist crimes remain against Joakim Medin, and he would, according to plan, be brought to court for them later.
Either the charges are dropped, but my tip is that they will continue with the trial in these matters where he gets a verdict in his absence, says Paul Levin.
The likely outcome is that Joakim Medin is sentenced to fines and that he will not be able to return to Turkey without risking imprisonment. It is, according to Levin, a signal to other journalists and experts who follow the Kurdish issue.
Political process
Also Aras Lindh, analyst at the Total Defence Research Institute, believes that Turkey's purpose with the arrest was to deter others from reporting on sensitive issues for the country. He believes that the release is the result of an entirely political process.
One must assume that contacts have been made at different levels and Kristersson also mentions European states in his statement that he says were "helpful in the process".
Do you think Sweden has made any concessions to get Medin released?
It's hard to say what it would be, I can't answer that.
Happy and surprised
Michael Sahlin, former Turkey ambassador, is happily surprised over the news. He is simultaneously very surprised that the release went so quickly.
This is fantastic for Joakim Medin and his family. Something special must have happened for this to be so quickly resolved. There was a German-Turkish journalist, Deniz Yücel, that Angela Merkel had to work on in a similar way for a year to get him free, he says.
It will be very interesting to find out what solved the issue.
