The National Police have refuted rumors regarding a possible terrorist plot in Indonesia, following a number of online reports that an alleged subdivision of hacker-activist group Anonymous had uncovered Islamic State (IS) movement plans to launch attacks around the world on Sunday.

National Police spokesperson Brig. Gen. Agus Rianto dismissed the rumors on Sunday, saying that the information could have been fabricated and disseminated by anyone with ulterior motives.

“What’s certain is that the police chief has instructed the entire force to increase security measures and encourage public participation to raise awareness about the issue,” Agus said.

… According to data presented in March by Nanyang Technological University terrorism expert Rohan Gunaratna, 19 of 27 militant groups in Southeast Asia that had declared their support for IS were from Indonesia.
