Spanish police on Tuesday arrested a man in the country's northeast who is suspected of spreading violent propaganda online, Spain's interior ministry said.
Officers from the Civil Guard detained the 25-year-old Moroccan citizen, who has been a resident in Spain since 2010, during a raid on his apartment in the north-eastern city of Zaragoza.
According to officials, he began his process of indoctrination in 2013 but had acted alone.
