The defendant was the subject of a European arrest warrant issued by a court judge of the Audiencia Nacional cooperating with the EU member states against terrorism, the Spanish Interior Ministry said. The man was the last member of a small group based in Belgium that had initiated in 2014 an important process of radicalization. The cell was composed of five other persons, three of whom were arrested by the Spanish authorities, two of them in Barcelona and Salou (province of Tarragona) on 8 May and another by the Moroccan authorities. Its members also included the detainee's younger brother, who was arrested in October 2015 for belonging to the terrorist organization. According to the investigators, the arrested man was the brain of this cell and organized indoctrination operations at his home or in cafes in Brussels. In addition to regularly sharing radical audiovisual content with other members, he also spread his ideology in various countries via social networks.
