JAKARTA, Sept. 23 (Xinhua) -- Indonesian police's anti-terror squad of Densus 88 arrested nine terrorist suspects in North Jakarta, West Jakarta and Jakarta's eastern outskirt city of Bekasi on Monday.
Police also confiscated rifle gun, pistol and high explosive bombs that the suspects assembled for attacks, said Indonesian National Police Spokesman Dedi Prasetyo.
All of the suspects are identified as members of the banned homegrown radical group of Jamaah Ansharut Daulah (JAD), which has stated its allegiance to international terrorist group of Islamic State (IS), according to the spokesman.
Dedi said a large number of assembled high explosive Triacetone Triperoxide (TATP) bombs were found in one of the suspects' residence in North Jakarta's Cilincing with the bomb materials procured through online app.
"Among the materials that he procured were acetone, measuring cylinder glass, hydrogen chloride and hydrogen peroxide," Dedi said.
One of the suspects already had plans to attack police stations, he said.
Another suspect was identified as the one tasked to recruit members of the banned organization and organize a training camp in Mount Salak in West Java province, he added.
Indonesia has banned the JAD last year and its leader Aman Abdurrahman was sentenced to death for masterminding several attacks in several cities of the country.
IS claimed responsibility for one of JAD attacks conducted in Central Jakarta's business district of Thamrin in January 2016 that killed four civilians and four perpetrators, and injured 24 others.
