The 32-year-old man was described as being in an “advanced state of radicalisation” and likened to terrorists behind recent attacks in the UK and France. Two other suspects he shared a flat with near to Madrid’s Atocha train station, two Moroccans aged 38 and 33, were also held in dawn raids today.

A spokesman for Spain’s National Police, referring to Isis by its acronym Daesh, said: “Officers have arrested a 32-year-old Moroccan man living in Madrid who belonged to the terrorist organisation Daesh and was in an advanced state of radicalisation. “He had an extremely dangerous profile, coinciding with those of the terrorists recently involved in attacks in the United Kingdom and France, and was considered an obvious threat to national security.
