Corruption Eradication Commission (KPK) leaders Agus Rahardjo and Laode M. Syarif faced terror threats on Wednesday, with unknown assailants placing what appeared to be bombs at their houses. It was suspected that a Molotov cocktail exploded at Laode’s house.

National Police spokesman Brig. Gen. Dedi Prasetyo confirmed the incident.

“We found evidence in the form of glass shards and trails of smoke, although we can’t confirm whether it was a Molotov cocktail or another type of bomb,” Dedi said.

According to a report obtained by The Jakarta Post, a bomb squad officer discovered a black bag hanging on the fence of Agus’ house in Bekasi, West Java, at around 5:30 a.m. on Wednesday.

The officer found material resembling components of a high explosive pipe bomb, such as a detonator, cable, nails and pipe. The bomb squad immediately defused the suspected package.

At the same time, the remains of a Molotov cocktail were found at Laode’s house in Kalibata, South Jakarta. The KPK deputy chairman claimed to have seen suspicious people near his house at around 1 a.m. through security cameras.

One of Laode’s neighbors said she heard glass breaking at around 1 a.m.

Dedi said personnel from the Jakarta Police, the National Police and the police’s Densus 88 counterterrorism squad were investigating the case.
