The National Police’s Densus 88 counterterrorism squad has arrested two men and a woman in Bekasi, West Java, for allegedly plotting a bomb attack at the State Palace in Central Jakarta.

The first two suspects, identified only as NS and AS, were arrested at around 3:40 p.m. on Saturday on the Kalimalang overpass, while the other suspect, a 27-year-old woman identified only as DYN, was arrested 10 minutes later at a rented house in Bintara Jaya subdistrict.

From the house, the police found a high-explosive bomb weighing around 3 kilograms packed into a pressure cooker.

“The bomb was to be detonated at the State Palace during the Presidential Security Detail’s [Paspampres] handover ceremony tomorrow [Sunday],” Jakarta Police spokesman Sr. Comr. Raden Prabowo Argo Yuwono said on Saturday evening.
