An Indonesian student suspected of carrying out a bomb attack at his school mosque in Jakarta wrote of feeling isolated in his 42-page diary and drew inspiration from a Telegram group glorifying white supremacist attacks, according to new details from police.



The early-November explosions struck worshippers as they lined up for Friday prayers, injuring 96 people and scattering shoes, prayer mats and glass across the courtyard.



Investigators have since combed through his internet history and raided his home to piece together how a reclusive 17-year-old in Muslim-majority Indonesia absorbed extremist ideologies with no historic influence in the country.



According to sources he got materials such as potassium chloride and nails from online marketplaces without setting off alarm bells, a security lapse police said they will examine closely.



Four of the devices detonated while three failed to explode.



The teenager joined an international Telegram channel where members shared violent material and discussed past attacks, including the 2019 massacre at mosques in Christchurch, New Zealand, and the 1999 shootings at Columbine High School in the United States.
