Videos widely circulated on social media showed students covering their ears while running for safety, some being carried on stretchers to waiting vehicles.
Most injuries came from burns, flying glass, sharp nails, and fragments from exploding objects. Parents waiting at Yarsi and Cempaka Putih hospitals described wounds on the head, feet, and hands of their children.
17-Year-Old Student Identified as the Suspected Perpetrator
Deputy House Speaker Sufmi Dasco Ahmad confirmed that the suspect is a 17-year-old male student who was among the two victims undergoing surgery due to severe injuries. National Police Chief Listyo Sigit Prabowo said investigators are examining the suspect’s home, background, and environment to understand how he assembled the objects found at the scene.
Police recovered a toy submachine gun bearing inscriptions such as “14 words. For Agartha” and “Brenton Tarrant: Welcome to Hell,” prompting investigators to explore whether the student had been influenced by extremist content. Authorities stressed that the markings were on a toy weapon and further analysis was needed.
Police Investigate Bullying Allegations and Possible Motive
Local media reported that the suspect was a Grade 12 student who had faced bullying and may have attempted a suicide attack. Jakarta Police spokesperson Budi Hermanto confirmed that officers are examining whether bullying contributed to the motive. However, he added that collecting witness statements has been challenging because many witnesses are hospitalized.

To support affected students and teachers, authorities have launched trauma-healing sessions at the school.
Blast Origin Near Mosque Loudspeaker Raises Technical and Criminal Questions
Jakarta Police Chief Asep Edi Suheri stated that the explosions came from near the mosque’s loudspeaker system. While the type of explosive used remains unknown, police deployed an anti-bomb squad to secure the area, inspect debris, and analyze possible triggers. Suheri repeatedly urged the public not to assume terrorism until investigations conclude.

Indonesia’s History of Attacks and Recent Security Landscape
Indonesia has previously faced major militant attacks, including the 2002 Bali bombings and later smaller strikes targeting police and government institutions. However, attacks on mosques are rare. Since 2023, the country has experienced what authorities describe as a “zero attack phenomenon,” credited to improved security operations. Recent violent incidents, including a deadly school building collapse weeks earlier, have put added pressure on emergency response systems.
