Initial reactions The alleged perpertrator is Muhammad Nazriel Fadhel Hidayat, a Year-12 student of the said school, aged 17 years old. He is known in school to have a quiet personality and a loner. He is also known to have an interest in far-right ideology, terroris, images of weapons, terrorism and videos depicting gore. This incident sparked concern from various parties, including the
Ministry of Primary and Secondary Education and the local government of Jakarta. A psychological recovery team was deployed to provide support to traumatized students, teachers, and school staff. Authorities urged the public not to spread speculation and to await the results of the official police investigation. Minister of State Secretary
Prasetyo Hadi said that President
Prabowo Subianto expressed deep concern over the incident and stressed the importance of taking swift action to ensure the safety of the victims. Authorities urged the public not to spread speculation and to await the results of the official police investigation.
Prabowo Subianto, through State Secretary
Prasetyo Hadi, stated that the government was considering restrictions on weapon-themed video games, which were considered a contributing factor to the explosion.
Prasetyo referred to the game
PUBG: Battlegrounds as dangerous for children. The minister of
Communication and Digital Affairs Meutya Hafid said that the results of the
Komdigi team's study found
elements of violence and even crime in the PUBG game.
Post-bombing investigations On 23 December 2025, a teenager was arrested in Garut for harboring both
far right-extremist and/or
far left-extremist ideologies and spreading bomb-making, weapon-making, and bullet-making materials. He spread the materials in a far-right terrorist
Whatsapp-based group and had successfully manufactured bombs and bullets, which were confiscated by the police. Locals revealed that the captured teenager was "gifted and a genius", speaking 7 languages, mostly talking in
Japanese and
Arabic. On 28 December 2025, based on his research and findings, Al Chaidar, a
terrorism researcher from
Malikussaleh University, estimated that the
Neo-Nazi network in Indonesia is around 300 men strong and almost all are under 17 years old, which he noted as strategy for their Neo-Nazi terror recruiters so the future attackers cannot be criminalized or put into adult judiciary if they committed the acts as "juvenile terrorists", and are thus given much lesser sentences. Al Chaidar urged the government to expand their deradicalization program to not only cover
Islamic terrorism, but also other dangerous extreme ideologies. He also recommended a government ideological mapping program to be developed further to map such extreme ideologies as the government did for
Islamist extremism. On 30 December 2025, criminologists of the National Counter Terrorism Agency (
BNPT) voiced similar concerns and requests for the BNPT to increase concerns regarding
far-right terrorism, despite the reluctance of the BNPT to classify the incident as terrorism. According to the BNPT, the attack lacked the organization and features of terrorism to classify it as such when compared to Islamic terrorism, which is more common in Indonesia. Following investigation into the Jakarta school bomber's internet circles, on 30 December 2025, police revealed there were 68 children and teenagers from 18 provinces also connected to him through a
Telegram community named the "
True Crime Community", where they were exposed to
white supremacism and
Neo-Nazi ideologies. Police also revealed that 20 planned school attacks subsequent to the Jakarta school bombing had been foiled by Densus 88 cyber patrols and proactive preventions. Police also uncovered 5 individuals that formed an unnamed Neo-Nazi network, which planned to indoctrinate 110 children and teenagers from 23 provinces by recruiting them through the Telegram community and
violent video games. On 7 January 2026, the Police announced that 70 children and teenagers from 19 provinces were discovered to have connections to Neo-Nazi and far-right extremist ideologies through various groups associated with
Terrorgram. 27 of them were located in
Jakarta and
West Java. Their ages ranged from 11 to 18, with the majority of them being 7th to 9th graders. All were capable of creating makeshift weaponry and
pipe bombs and were also capable of arming themselves for sudden attacks. Some had already created plans for attacks on schools, involving methods such as mapping and disabling
CCTV systems, planting bombs in classrooms, and how to kill their own classmates and teachers. One suspect was able to produce detailed manuals and tutorials for
bomb-making in English. As they are juveniles and had yet to carry out any attacks, Police chose to assess, map, and send them for counselling as a preventive measures. On the same day, Police found the connection between the bombing with
Odintsovo school attack that happened on 16 December 2025. On the knife handle used by the Timofey Kulyamov, perpetrator of
Odintsovo school attack, the words "2025 Jakarta Bombing" were written, referring the Jakarta school bombing. On 7 January 2026, the police also announced a list of 27 Indonesian Neo-Nazi
Terrorgram circles. Sources also said, Indonesian neo-Nazi circles has connections with Malaysian neo-Nazi far-right groups such as Nusantarist, Malay Power 1388, Darah & Maruah Tanah Melayu and Nusantarawingism. Including few of the infamous Malaysian Neo-Nazi activists, Karl, Zordiel, Alek, who promoted anti-
Rohingya sentiments and
Malay supremacism online.
Subsequent attack On 3 February 2026, a 9th-grader junior high school student at SMPN 3 Sungai Raya,
Sungai Raya,
Kubu Raya,
West Kalimantan, committed an arson attack in the school yard using a
molotov cocktail during free lunch time. No casualties reported. In his backpack were various symbols, numerology (likely referencing the number of victims in various mass-casualty events), sigils, and names of previous attackers, such as
Adam Lanza,
Seung-Hui Cho,
Salvador Rolando Ramos,
Timur Bekmansurov,
incel-
misogynist murderer Elliot Rodger,
Las Vegas attacker Stephen Paddock,
Orlando attacker Omar Mateen, and
2019 Sri Lanka Easter bombings mastermind
Zahran Hashim. The school bomber also connected with the same "True Crime Community" Neo-Nazi terrorgram circle like previous SMAN 72 Jakarta bomber. Authorities noted while the suspect's behaviour was normal at school, they believed he had mental issues related to his familial situation, as his father and grandfather had illnesses == See also ==
