[2][3][4][5] On September 17, 2008, he publicly announced that he had 'robbed' dozens of Spanish banks of nearly half a million euros as part of a political action to denounce what he termed the predatory capitalist system.
[9] In 2009, Duran returned to Spain, and was arrested by Spanish police on March 17, 2009, at the University of Barcelona, as charges had been brought against him by six of the thirty-nine banks concerned.
[10][11] For the first anniversary of the announcement of his "robbery", an action day was planned in over 100 cities on September 17, 2009, in which people met, both in Spain and abroad, to share alternatives to capitalism.
On November 25, 2011, the state prosecutor requested that the judiciary pass down an 8-year prison sentence for Duran, for the crimes of presenting false documents (in securing his loans) and continued insolvency.
He questioned the state's lack of response to the financial speculators who inflicted great suffering on much of the European population, and to the September 2011 changes to the Spanish constitution which made the repayment of debts the absolute priority of the country.
[citation needed] Duran cited the pardon granted to the chief executive of the Banco Santander, Alfredo Sáenz Abad, in November 2011, as an example of the bias of the judiciary towards the powerful and well-connected, and argued that "when the government violates the rights of the people, insurrection is the most sacred of rights and the most indispensable of our duties" (translated from Catalan).
He called on his supporters not to waste time campaigning for his acquittal or release, but rather to follow his acts of civil disobedience towards the banks with their own.
