The arrest took place in Chemin de Sopite, in Hendaye (France). A European Arrest Warrant issued by Criminal Investigation Court Number 2 of the Spanish National High Court was outstanding against him for an offence relating to collaboration with an armed gang.
Iñaki Imaz Munduate, one of the most-wanted members of ETA, formed part of the "political wing" of ETA (the structure that currently runs the terrorist gang). He used to maintain contact with the leading committee (known internally as 'ZUBA') on the one hand and with the clandestine structures located in southern France on the other to provide sporadic support and advice of a technical nature.
His activity supposedly contributed to the materialisation of extensive communications from ETA following its declaration in which it claimed to definitively cease its armed activity on 20 October 2011.
Iñaki Imaz Munduate was born on 7 December 1978 in San Sebastian. Until a few months ago, he had been living in hiding in Ireland with false documentation provided by ETA. His presence in Ireland was allegedly a response to the strategy designed by the terrorist group to relocate a part of its clandestine structure so as to avoid the police pressure being experienced in France.
The man arrested on Monday previously formed part of the 'Donosti unit' as a 'legal' member. His work consisted of offering his flat in San Sebastian to house José Ángel Lerín Sánchez ("Jaxinto"), an 'illegal' activist and the man responsible for said terrorist group. It should be pointed out that Ignacio Lerín Sánchez ("Belea"), a fellow 'unit' member of Iñaki Imaz Munduate, was arrested in London (United Kingdom) on 29 June.
Various weapons and ammunition were also being stored at the flat in San Sebastian and hand-written documents by Iñaki Imaz Munduate in preparation for future attacks were found. These documents include schedules followed by members of the National Police Force with access to the Aldapeta Barracks in San Sebastian; the address of the parents of a member of the 'Ertzaintza' (Basque Police Force) in San Sebastian; information on a petrol station used by vehicles of the State Security Forces; a workshop where the Guardia Civil left vehicles for repair; and information on the movements of various local councillors from Pasajes de San Juan (Guipuzcoa).
Iñaki Imaz Munduate was also responsible for producing "Zutabe" (the internal ETA bulletin in which strategic lines of action are reported and calls are made to undertake terrorist activities) on premises in the Errotaburu district of San Sebastian.
18 members of the terrorist gang ETA have been arrested so far this year.
