Carles Puigdemont was detained in Germany on March 25, when he was crossing the border from Denmark, on his way to Belgium from Finland.
Former Catalan President Carles Puigdemont had left Finland before the country's police could arrest him in line with an arrest warrant issued by Spain, Puigdemont's lawyer Jaume Alonso Cuevillas announced earlier. The ex-head of Catalonia is currently being held at a police station.
At the same time, Puigdemont said earlier in the week that he was ready for talks with the central government, and believed that his return would be evidence of the normalization of politics and democracy in Spain.
Spanish authorities have opened a criminal case against 30 Catalan politicians and officials, arresting four of them, while Puigdemont, as well as several advisers of the dissolved Catalan government, fled Spain before the trial.
