According to the investigation, the suspect "made intensive use of social networks in order to view and disseminate information with jihadist content," the police added in a statement.

 After monitoring his activities, the Spanish security services revealed that the individual had assumed Daesh's virtual strategy, by adopting the terrorist organization's postulates through a process of self-indoctrination and mass dissemination of their contents on the Internet.

 He also possessed "numerous jihadist documents, including videos of training in military camps and testimonies of martyrs," the same source noted.

 The suspect took scrupulous security measures to avoid detection by the police through using several fake profiles on highly confidential social networks and instant messaging platforms, which allowed him to be in direct contact with Daesh terrorists in the battlefields in Syria, explained the Spanish police.

 The individual, who left his job to devote himself entirely to the consolidation of his training, dissemination and indoctrination activities, had made public his membership of Daech, presenting himself as a "son of the Islamic State".

 Threats made by the suspect on social networks against Spain and other countries precipitated his arrest, thereby neutralizing the "serious threat he posed to national security," the statement concluded.
