Former Catalan president Carles Puigdemont has been detained at the German border while making his way to Belgium from Finland, his lawyer said on Sunday, wrote telegraph.co.uk.
On Saturday Mr Puigdemont foiled attempts by Finnish police to arrest him under a European arrest warrant which was reactivated by a Spanish Supreme Court judge on Friday.
Mr Puigdemont is wanted by Spain on charges of "rebellion" and "sedition".
Mr Puigdemont, who lives in self-imposed exile in Belgium, had been visiting Finland since Thursday for talks with lawmakers.
Tensions are running high in Catalonia and separatist parties have abandoned plans to name a new president following the arrest of the latest candidate.
