Prosecutors in Germany say that fugitive Catalan ex-president Carles Puigdemont will appear in court Monday in a northern German town "to confirm the identity of the detained.''
The Schleswig prosecutor's office said in a statement that "the question of whether Mr. Puigdemont has to be taken into extradition custody, will then have to be determined by the higher regional court in Schleswig.''
The statement says that the court will check, based on extradition documents by Spain, if the handover of Puigdemont to Spanish authorities is "legally permissible.''
Puigdemont was detained Sunday morning in Germany on an international warrant near the highway leading from Denmark to Germany.
He fled from Spain in October following an illegal declaration of independence by the region.
