Spanish public prosecutors on Monday asked a judge investigating Catalonia's former president Carles Puigdemont to re-issue a European arrest warrant for him, a judicial source said.

The judge is not obliged to grant the request which comes as Puigdemont, who fled to Belgium to avoid prosecution over his role in Catalonia's independence drive, arrived in Copenhagen. 

Puigdemont and the rest of his ousted government have been charged with rebellion, sedition and misuse of public funds.
