I read your news of Singapore government arrest four people for want to join ISIS terrorist group. The report say these people get brainwash after listen to radical Batam radio station Radio Hang. They say that preacher on radio Hang spread extreme ideas to their listeners. I was read your facebook and see some people argue say Radio HANG is not extreme views. They say they listen in to Batam's Radio HANG and never listen to any extreme preaching at all.
