German prosecutors yesterday asked a court to order the extradition to Spain of Catalonia's ousted president Carles Puigdemont on a rebellion charge following his arrest in Germany last month.

The request comes after demonstrations by independence supporters at the weekend in Berlin and Catalonia calling for Puigdemont's immediate release

“The prosecutor's office of Schleswig-Holstein state applied for an extradition arrest warrant against former Catalonian regional president Carles Puigdemont from the superior regional court, “ it said in a statement.

It was not immediately clear when the court would rule on Puigdemont's possible extradition.

Puigdemont was arrested by German police on March 25 as he was travelling from Finland back to Belgium, where he has been living in self-imposed exile since Catalonia’s failed independence bid last October.

The detention came two days after a Spanish judge issued European arrest warrants for Puigdemont and other fugitive separatist leaders. They have been ordered to stand trial for rebellion, misuse of public funds and disobeying the state for organising last year's referendum on Catalan independence, which Madrid deemed illegal.

German media say the request has been complicated by the fact that rebellion, which carries a maximum penalty of 30 years in jail in Spain, is not a crime under German law.
