A coordinated operation involving Spain's Guardia Civil, the Basque autonomous police (Ertzaintza), and the Catalan Mossos d'Esquadra has resulted in the arrest of a 17-year-old Spanish national in Gipuzkoa, near the French border. The teenager is believed to be the principal Spanish figure of the 764 network, a group linked to neo-Nazi, paedophile, and satanic activities.
According to investigators, between January and April of this year, the suspect sent numerous messages threatening armed attacks on schools, town councils, libraries, and other public and private institutions across Spain. Although none of the attacks were carried out, the threats were credible enough to trigger exceptional security protocols at several locations. In some messages, the author allegedly claimed he would broadcast the attacks live for other network members to watch.
The arrest follows a joint investigation that included searches of two homes in Gipuzkoa on 16 July, conducted with judicial authorization. Electronic devices, storage media, and documents were seized and are now being analyzed. The detainee has appeared before a judge and has been placed in a specialized juvenile detention centre in Donostia/San Sebastián.
What is the 764 network?
The 764 network originated in the United States, named after the first three digits of the postcode of Stephenville, Texas, the hometown of its founder. Initially a marginal online community, it has evolved into an international structure involved in sextortion, distribution of child sexual abuse material, incitement to self-harm, and dissemination of extreme violence and animal abuse content. Canada has designated it a terrorist entity, and several countries are investigating its activities.
In Spain, the investigation has uncovered the use of techniques such as swatting, doxing, and identity theft, aimed at falsely implicating innocent people to provoke police interventions and divert attention. At least two individuals, one in the Basque Country and another in Catalonia, have been subjected to harassment campaigns as a result.
The suspect is also accused of participating in digital spaces where psychological manipulation was exerted on children and vulnerable young people. Victims were coerced into self-harm and submission, with images and videos later shared within the community to maintain control over them.
Prevention and awareness
Authorities emphasize that networks like 764 actively target minors on social media, messaging apps, and gaming platforms. Initial contact often appears as friendship or shared interests, but gradually escalates into manipulation, blackmail, and isolation from the victim's support network.
Police recommend that families and educators remain vigilant for warning signs such as requests for private photos, secretive online behavior, proposals involving self-harm, or demands to participate in degrading challenges. Early intervention is crucial to prevent exploitation.
The case highlights the growing challenge of online radicalization and child exploitation across Europe. As investigations continue, Spanish authorities are working with international partners to dismantle the network's operations.
