Moroccan National Police and territorial surveillance agents arrested a 22-year-old suspected extremist in Tangier after forensic tests found chemicals used to make explosives, including TATP. The suspect was detained on October 9, and laboratory checks carried out in Casablanca also pointed to preparations that involved experimental detonations tied to possible terrorist attacks. In a joint statement, the security agencies said the National Police Scientific Laboratory examined seized items and electronic devices using physical and chemical tests plus digital forensics. Investigators reported the presence of multiple explosive-related substances, including triacetone triperoxide (TATP), urea fertilizer and a nitric acid solution that can be used to produce urea nitrate, and strong chemical powders linked to explosive mixtures. They also found an oxidizing substance associated with chlorates used in explosive charges. Police said the haul included equipment and materials consistent with preparing explosive devices, such as acetone, acidic solutions, electrical components, batteries, wires, switches and metal objects. Investigators also described nails and screw heads that could act as shrapnel, along with adhesive tape and welding goggles. Digital forensic work focused on a mobile phone seized from the suspect. Authorities said the phone had been modified with electronic circuits and electrical connections, and that its operating system had been altered so it could function as a mechanism for activating an explosive device. The Central Bureau of Judicial Investigations led the probe under the supervision of the competent public prosecutor’s office, with investigators also finding handwritten materials that included methods for cyber intrusion. The suspect remains under investigation following the arrest in Tangier.
