He is best known as the head of the military/commando unit of the group since late 2008 until April 18, 2009, when he was arrested by French police. He is considered to be one of the most dangerous members of ETA, considered a terrorist organization by the European Union, with police describing him as "extremely violent". He gained prominence in the military section of ETA by leading the 'commando Vizcaya' (Biscay Command) after the 2006 ceasefire along with Arkaitz Goikoetxea and rose to the highest level of ETA's military leadership following the December 2008 arrest of Aitzol Iriondo alias Gurbita who had replaced Miguel de Garikoitz Aspiazu Rubina alias Txeroki, arrested less than a month before.
