Former Catalan president Carles Puigdemont was tracked by Spain through fitting his group's car with a surveillance device as well as following the mobile phones of his companions. He was eventually captured in Germany on his way to Belgium from Finland.
Spanish intelligence agents had been tracking the movements of the former Catalan president Carles Puigdemont using the geolocation service on his friend's mobile phone before he was detained in Germany at the weekend, according to reports.
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.

An international warrant for Puigdemont's arrest had been rescinded back in December but was revived for this occasion. Already back in September, the Internet Society issued a statement about the Spanish government's great efforts to outright censor online activities promoting or discussing the bid for Catalonian independence.
