READ MORE: Former Catalan President Puigdemont Detained in Germany

Puigdemont's arrest sparked protests across Catalonia, with about 50,000 people taking to the streets to show their support for their former leader. Puigdemont was detained under a European arrest warrant in the northern German province of Schleswig-Holstein on Sunday morning as he journeyed by car from Helsinki to Brussels, where he has been living in self-imposed exile since Catalonia’s unilateral declaration of independence last October. Puigdemont had been visiting Finland since Thursday for talks with lawmakers, but when the car left Waterloo on Friday morning and began travelling north, they suspected that Puigdemont was planning to return to Belgium by car.
The Spanish National Police Corps arrest the two Mossos d'Esquadra and Asia History academic, Josep Lluís Alay, who accompanied Puigdemont in the van at the moment he was detained in Germany amid a crime of concealment. On 28 March were released.
