Spain’s Interior Ministry says three Moroccans, including one suspected of membership in the Takfiri Daesh terrorist group, have been arrested.
The ministry said in a statement on Wednesday that police arrested the main suspect, a 32-year-old, during a raid on a residential apartment in the neighborhood of Las Delicias in Madrid.
He was described as being "in an advanced state of radicalization" and was in possession of "an extensive ideological and electronic library of numerous manuals on jihadist terrorism," including specific manuals on suicide bombing.
"He had an extremely dangerous profile, similar to that of terrorists recently implicated in the attacks in Britain or in France," the statement added.
The ministry said he was "an obvious threat to the security of our country" as he intended to recruit others to conduct acts of terror in Spain.
The other two Moroccans were living with the 32-year-old suspect.
Spain has been on a high terror alert for the past two years.
According to the ministry, at least 69 people were arrested in 2016 as part of the fight against terrorism. More than 35 people have been arrested this year.
In March 2004, Madrid was hit by coordinated train bombings by an al-Qaeda inspired group. More than 190 people were killed.
