Two of the arrested have admitted illegally taping conversations of members of Catalonia's Partito Popolare.
Partido Populare President, Alicia Sanchez Camacho, last week filed a complaint with police after claiming that a dinner in a Barcelona restaurant on July 7 2010 between herself and Victoria Alvarez, the ex girlfriend of Jordi Pujol junior, the son of former Catalan premier Jordi Pujol, was bugged.
In the illegally obtained recordings Alvarez was heard telling Camacho about alleged money laundering: 500 euro bank notes were stuffed in a suitcase bound for Andorra and her then boyfriend made threats not to reveal details of his family's money laundering activities. Sanchez Camacho alleges that the spying is politically motivated, given that the sister of Metodo 3 director Elisenda Villena, 'Ana' is head of justice in the Catalan Socialist Party (PSC).
Camacho hit back at criticism for not going to the police about Alvarez, by calling her story ''incomplete and inconclusive''. (ANSAmed).
