Latest research published in the CTC Sentinel by the Combating Terrorism Center examines a series of attacks and alleged plots involving minors, suggesting Italy has entered a new phase in confronting nihilistic violent extremism and digitally driven youth violence.
A series of school attacks and alleged attack plots involving children and teenagers has prompted Italy to confront an emerging form of violent extremism that security experts argue differs significantly from both traditional terrorism and ordinary juvenile delinquency. According to research published in the latest issue of the CTC Sentinel by the Combating Terrorism Center, the incidents collectively represent Italy’s first publicly visible sequence of cases linked to nihilistic violent extremism (NVE), the True Crime Community (TCC), and related online subcultures centred on performative violence.
Drawing on official statements, specialist research and open-source reporting, the study examines four incidents that unfolded between March and May 2026, together with a significant precursor case from February 2025. While each episode involved unique circumstances, the authors argue that they reveal a broader pattern shaped by transnational online communities, imitation, livestreaming, and a culture that often prizes notoriety and aesthetic symbolism over coherent political ideology.
The sequence began on 25 March 2026 in the northern Italian town of Trescore Balneario, where a 13-year-old student stabbed his French language teacher inside a school after publishing a pre-attack text entitled The Final Solution and attempting to livestream the assault on Telegram. Just over two months later, on 29 May, another boy, aged 12, attempted to stab his technology teacher in San Vito Lo Capo, Sicily, while wearing a helmet covered with references to school attackers and the True Crime Community and intending to broadcast the incident online.
Between those attacks, Italian authorities disrupted two separate alleged school attack plots involving teenagers. On 30 March, police arrested a 17-year-old in the province of Perugia who was reportedly fascinated by neo-Nazism, incel ideology and school shootings, and was accused of planning a Columbine-style massacre. Only days later, investigators searched a 15-year-old in the province of Arezzo who allegedly admired the Trescore Balneario attacker and had reportedly expressed interest in carrying out a similar assault.
According to the study, these events should not be viewed in isolation. Instead, they appear to reflect the growing influence of online ecosystems that combine elements of nihilism, school-shooting mythology, misogynistic grievance, violent extremist symbolism and internet fandom into a shared culture that encourages imitation and competitive escalation.
The authors also identify an important precursor dating back to February 2025, when Italian police arrested a 15-year-old near Bolzano on allegations including participation in a terrorist organisation, explosives offences, weapons violations and possession of child sexual abuse material. Investigators reportedly linked the teenager to the transnational online network known as 764, a loosely connected ecosystem operating at the intersection of violent extremism and child exploitation.
According to Italian investigators, the teenager had allegedly planned to murder a vulnerable victim as part of what members referred to as a coordinated “Terror Week”, recording the killing for distribution within the online network. Authorities also reported recovering extremist propaganda, improvised explosive devices, violent material, child sexual abuse content and evidence suggesting an extensive online relationship with individuals linked to the wider 764 network.
The study argues that the Bolzano case demonstrated Italy’s exposure to transnational online extremist communities long before the more visible sequence of school incidents emerged in 2026.
One of the article’s central arguments is that nihilistic violent extremism differs fundamentally from conventional ideological terrorism. Rather than being driven primarily by coherent political or religious beliefs, many participants appear motivated by personal grievances, status-seeking, spectacle, aesthetic identity and recognition within online communities.
In the Trescore Balneario attack, for example, the alleged manifesto mixed personal resentment towards a teacher with repeated references to uniqueness, revenge and breaking societal norms. Although it incorporated language and imagery associated with extremist movements, investigators found little evidence that the attacker adhered consistently to any single political ideology. Instead, the symbolism appeared to function largely as a vehicle for transgression and online performance.
Similarly, the San Vito Lo Capo attacker reportedly covered his helmet with references to notorious school shootings, mass casualty attacks and violent offenders from several different ideological backgrounds. According to the researchers, such collections of symbols are characteristic of the True Crime Community, an online fandom that studies, aestheticises and sometimes seeks to emulate perpetrators while often paying comparatively little attention to their underlying ideological motivations.
The study argues that these communities create a distinctive communicative environment in which attacks are designed not only to harm victims but also to generate digital audiences through livestreams, photographs, manifestos and post-attack memorialisation. Violence itself becomes performative, with participants seeking recognition from online peers who reward notoriety, symbolism and imitation.
Investigators are also examining possible connections between the Trescore Balneario and San Vito Lo Capo cases. Although direct communication between the two boys has not been confirmed, the younger student reportedly reshared material celebrating the earlier attack and even wrote the surname of the first attacker on his helmet. The study suggests this may represent Italy’s first publicly visible example of a domestic mimetic chain associated with nihilistic violent extremism, in which one attack rapidly inspires another without evidence of formal organisational coordination.
The authors note that imitation has long been recognised within terrorism studies, but argue that NVE places particular emphasis on aesthetics, online fandom and competitive replication rather than sustained ideological indoctrination. This can significantly shorten the period between one incident and another, creating challenges for authorities attempting to intervene before violence occurs.
Another recurring feature identified across the Italian cases is the extensive evidence of “leakage”, whereby potential attackers communicate their intentions before acting. Manifestos, photographs, social media posts, hashtags, Telegram messages and other digital signals were reportedly visible before several of the incidents examined in the study.
The researchers argue that these warning signs highlight the need for closer cooperation between schools, families, mental health services, law enforcement agencies and technology platforms, while cautioning against treating every instance of adolescent provocation as evidence of terrorism.
The exceptionally young age of many of those involved presents another major challenge. Two of the principal attackers were aged just 12 and 13, placing them below Italy’s minimum age of criminal responsibility. According to the study, both appeared aware of the legal protections associated with their age, with one reportedly referring to them in his pre-attack writings.
At the same time, the authors stress that these children should not be viewed solely through a criminal justice lens. Many appear simultaneously to be vulnerable minors experiencing profound personal crises while also posing genuine risks of serious violence. Effective responses, they argue, therefore require not only policing and counterterrorism capabilities but also long-term prevention, rehabilitation and community support.
The study also highlights Italy’s lack of a comprehensive national strategy for preventing and countering violent extremism, arguing that the country’s historically successful counterterrorism record may have reduced the perceived urgency of developing broader prevention frameworks. However, the recent sequence of incidents demonstrates that new forms of digitally mediated violence demand approaches extending beyond traditional security responses.
Despite the seriousness of the threat, the authors point to one encouraging example. The teenager arrested near Bolzano in 2025 reportedly entered a court-supervised rehabilitation programme and, according to later reporting, had become engaged in education and expressed gratitude to authorities for intervening before he carried out his alleged plans.
The researchers conclude that Italy’s recent cases are not isolated anomalies but the national manifestation of an increasingly transnational phenomenon shaped by online networks, imitation and performative violence. They argue that nihilistic violent extremism occupies a complex space between terrorism, targeted violence, child exploitation, youth mental health and digital culture, making simplistic classifications inadequate.
Ultimately, the Italian experience illustrates both the evolving nature of contemporary extremist threats and the growing importance of early intervention. As online communities increasingly shape the pathways through which vulnerable young people encounter and glorify violence, the study concludes that preventing future attacks will depend not only on effective law enforcement but also on building comprehensive systems capable of identifying at-risk children early, interrupting harmful online influences and providing meaningful opportunities for rehabilitation before fascination with violence becomes real-world action.
