ISIS Supporter Arrested in Spain: Police Find Bomb-Making Materials and Target List

During the searches carried out on Saturday, the police discovered a large number of chemical substances, including ammonium nitrate, hydrogen peroxide and methylcyclopropane, which are used to prepare TATP, the explosive favored by jihadists.

Worse, a detailed list of target persons and infrastructures made it possible to link him to the author of all the videos that conveyed threats on the internet between the end of 2018 and 2019.

The young Moroccan "has an in-depth knowledge of computer security, allowing him to make terrorist threats while concealing his identity and digital footprint," the police said in a statement. This allowed him to "complicate efforts to identify and locate him."
