The casualties include the suicide bomber and one policeman, National Police Chief General Listyo Sigit Prabowo said.

"One of our personnel who had sustained serious wounds died," Sigit said.

The police chief said that the perpetrator of the bombing was identified as Agus Sujatno. The man was affiliated to the Jemaah Ansharut Daulah (JAD) of West Java province which is linked with the suicide bombings in East Java in 2018.

The police found several pieces of evidence at the scene, including a sheet of paper indicating protest against a newly endorsed criminal code outlawing sex outside marriage.

Provincial police chief Suntana said that eight police personnel were wounded in the blast, and another was a civilian, who was walking by the scene.

The wounded have all received medical treatment at a nearby hospital, according to him.
