However, there was no indication of RA being involved in a particular terrorist network.
"This perpetrator is a suicide bomber. RA has been exposed to the radical teachings of ISIS," Brigadier General Prasetyo stated at the National Police Headquarters, Jakarta, Tuesday.
RA's identity was established through fingerprints that matched with those on his certificates.
"RA's identity came to light after verification of his fingerprints and the certificates," he revealed.
Prasetyo elaborated on the identity of the young, unmarried male perpetrator RA, aged 22, holding a private job and senior high school education and address traced to Wirogunan, Kartasura, Sukoharjo, Central Java.
