German prosecutors filed a request on Tuesday for the extradition of Catalan leader Carles Puigdemont to Spain. Prosecutors said Spain's extradition request was admissible and Puigdemont should be detained because he is considered a flight risk. He has been imprisoned in Germany since his arrest on March 25th. Now almost all former Catalan leaders are behind bars before trial, or in exile. On Monday, Puigdemont appealed the charges of rebellion, and denied any wrongdoing.
