Puigdemont walks out of jail, but he has to stay in Germany while court continues to examine Spain’s extradition request
The request comes after protests by independence supporters at the weekend in Berlin and Catalonia calling for Puigdemont's immediate release.
Huddled under umbrellas in the rainy German capital, the protesters walked from Brandenburg Gate to the justice ministry, carrying banners that read "Free Puigdemont and the Catalan political prisoners" and "Spain is not a democracy".

Puigdemont "was arrested today at 11:19 am by Schleswig-Holstein's highway patrol force," a German police spokesman told AFP, adding that the detention was based on a European warrant.
Puigdemont, who lives in self-imposed exile in Belgium, had been visiting Finland since Thursday for talks with lawmakers.
