"They had hatched a plan to attack Singapore by firing a rocket from Batam," head of the national polices public information bureau, Brigadier General Agus Rianto, said here on Friday.
He informed that GRD was to execute the plan in cooperation with Bahrun Naim, an ISIS fighter from Indonesia. "The plot was likely hatched before BN (Bahrun Naim) left for Syria," he added.
GRD is also believed to have planned a number of bombings at busy locations and police stations.
Agus pointed out that GRD is the leader of a terrorist group, named "Kitabah Gonggong Rebus."
The polices anti-terrorist Densus 88 squad arrested GRD and five other KGR members in Batam on Friday.
"We arrested six terror suspects who were members of the Kitabah Gonggong Rebus from Batam on Friday morning," he said.
They were caught from different locations. GRD (31), Tar (21) and ES (35) were nabbed from the Batam Center while TS (46) was caught in Nagoya and HGY (20) and MTS (19) from Batu Aji.
They are now still being intensively interrogated to determine their respective roles, Agus disclosed.(WDY)
