Brig. Gen. Boy Rafli Amar, national police spokesman, said detectives are prepared to release a sketch of the suspect, described by witnesses as a 5-foot-4 male wearing a helmet. Security footage from the ATM shows the suspect entered the glass vestibule of a Bank Mandiri branch in Malang, East Java, Thursday and leaving behind a black box with a fuse.
Moments later the bomb explodes, hurling glass for more than 60 feet onto the street, the Jakarta Globe reported Friday.
No injuries were reported.
Police said they suspect the bombing was the work of a terrorist and said the explosive used were consistent with that theory. They have interviewed four people who were in the vicinity in the moments before the explosion.
