The ten suspects were arrested in Banten, North Sumatra and West Java, police spokesman Sr. Comr. Martinus Sitompul said here on Thursday.
Martinus identified them with their initials SU, S, K, A and M caught in Banten, saying SU was arrested in Cilegon and the other four in Serang, Banten.
Three - R, J and A, were picked up from their places in Medan, North Sumatra and two MA and WT were nabbed in Bandung, West Java.
The ten men belonged to terrorist group of Jamaah Ansharut Daulah (JAD) of different cells, Martinus said.
"This is a preventive measure before they are ready to launch attacks such as the recent suicide bombing in Kampung Melayu, Jakarta," he said.
Suicide boming last month in the bus terminal in Kampung Melayu left five people dead including three police officers and the two bombers.
JAD in Indonesia was headed by Aman Abdurrahman, who is now serving jail term in Nusakambangan, Cilacap, Central Java. The leadership has been taken over by Zaenal Ansori, who recently was arrested by police in Lamongan, East Java.(*)
