"This suicide bomber wore the bomb around his waist, so when the bomb went off, he suffered injuries to his stomach and right hand," Prasetyo stated at the National Police Headquarters in Jakarta on Tuesday.
The National Police's Counterterrorism Squad, Densus 88, conducted a search of RA's house in Kranggan, Wirogunan Village, Kartasura Sub-district, Sukoharjo District, Central Java, on early Tuesday.
During the search, Densus 88 officers along with their counterparts from the Central Java Provincial Police confiscated several pieces of evidence believed to be employed in assembling a bomb.
Prasetyo cited that results of examination at the scene of crime and based on several pieces of evidence seized from RA's house, the police arrived at a conclusion that RA had deployed a low-explosive bomb.
"The bomb is of a low-explosive type. It is discovered from the remnants of explosive powder collected from around his abdomen and trousers that later matched with those found at his house, so we conclude that the bomb is a low-explosive variety. This is a suicide bombing attack," he revealed.
The Densus 88 anti-terror squad seized several items of evidence from RA's house comprising two bags of sulfur powder; one bag of potassium chlorate; two bags of mixture powder of sulfur, potassium chlorate, and charcoal; two plastic bags of cables; and one plastic bag of charcoal, a nine-volt battery, a 3.7-volt battery charger, 2.5-cm diameter pipe, manual detonator, solder, and splinters of nails.
The suicide bomber RA is a 22-year-old single man. RA was a private employee residing in Wirogunan, Kartasura Sub-district, Sukoharjo District, Central Java.
After the bombing, RA was reportedly taken to PKU Muhammadiyah Hospital in Kartasura for treatment.
The man, with injuries to his stomach and right hand, was later referred to the Mawardi Regional General Hospital in Surakarta, Central Java.
No lives were lost in the suicide bombing incident. The police have sterilized RA's house and placed a police line around it.
