A 17-year-old has been arrested in Gipuzkoa, northern Spain, accused of running the country’s section of 764, the international network that fuses neo-nazism, Satanism and the sexual exploitation of children.
Investigators regard the teenager as the main contact point for 764 in Spain. He is accused of sending a death threat earlier this year to Podemos MEP Irene Montero and broadcaster Sarah Santaolalla.
The message to Montero identified her home address where her children and partner live, and threatened to murder her there.
Wave of threats
Police have also linked him to a wave of threats sent between January and April against schools, town halls, libraries, community centres and public bodies, some accompanied by promises to livestream the resulting killings for the network’s members.
None of the threatened attacks materialised, but they triggered extensive security operations across the region.
Searchlight has recently reported on one British offshoot of this same milieu.
The case of Rex Clark and Sofija Vinogradova, the Cheshunt and Ilford teenagers prosecuted after a Tinder relationship curdled into neo-nazi trolling, ran through the No Lives Matter network, a spinoff of 764, whose founder, Bradley Cadenhead, is serving 80 years in Texas for coercing children into sexual acts and self-harm.
764 was founded in the United States in 2021 and has since expanded from a small online community into an international network operating across several countries.
Federal charges against Cadenhead described a Telegram-based network soliciting hate crimes and assassinations linked to attacks in Slovakia, Brazil and Turkey.
Its members groom vulnerable young people on gaming platforms and social media, drawing them into private groups where they are coerced through blackmail, sextortion and psychological manipulation into self-harm and acts of extreme humiliation, filmed as proof of the recruiters’ control.
Canada became the first country to proscribe 764 as a terrorist entity in December 2025.
The UK proscribed related “Com”-network offshoots, including Maniacs Murder Cult and the Terrorgram Collective, under the Terrorism Act in 2024, though 764 itself remains unlisted here.
Real world violence
The ban on Terrorgram was the first time an online-only network had been banned under the Act.
The Maniac Murder Cult case in Sweden, where prosecutors detailed a cell recruiting teenagers into filmed self-harm and animal cruelty as initiation rites, revealed the same pattern of online grooming escalating into real-world violence years before Spanish police caught up with 764.
