National Police chief Gen. Badrodin Haiti confirmed that the police captured an alleged terrorist in Bekasi, West Java on Wednesday morning.
"It is true. This morning we busted a suspected terrorist, alleged to have been plotting attacks this month," he said as quoted by news agency Antara on Wednesday.
The alleged terrorist, identified only by the initials AM, was captured by the National Police's counterterrorism detachment Densus 88.
AM is suspected to have an established relationship with the IS associated terrorists captured in Sukoharjo and Tasikmalaya on Dec.19 and Dec. 20. "These arrests relate to the Islamic State (IS) group in Syria," said Badrodin.
Separately Australia had warned Indonesia of the possibility that the IS network would form a caliphate in Indonesia.
Badrodin had said earlier that the police had arrested nine suspected terrorists from various areas such as Cilacap, Tasikmalaya, Sukoharjo, Mojokerto, and Gresik on Dec. 19 and Dec. 20.
These alleged terrorists were identified by the initials R, YS, AR, ZA, MKH, TP, IM, JA, and AK.
"They are former members of Jamaah Islamiyah", he said, adding that, at the end of November, the police had received information from the Australian Federal Police (AFP), the US Federal Bureau of Investigation (FBI) and the Singapore Intelligence Service (SIS) that there would be terrorism actions in Indonesia.
In response to the information, the police had started to monitor suspect groups alleged to be involved in acts of terrorism.
