“Anything that can help find [the people] should be done. We have Interpol and other [international] law enforcement agencies,” Prasetyo told reporters on Wednesday as quoted by Kompas.com.

The anti-graft body has planned to question Sjamsul as a witness in the case, however the plan has not materialized because Sjamsul is reportedly in Singapore.

Sjamsul, who is the owner of Bank Dagang Nasional Indonesia (BDNI), will be questioned over Rp 3.7 trillion (US$277 million) of debt owed to the state, which he allegedly failed to return despite receiving a settlement letter from Syafruddin Arsyad Temenggung, a former chairman of the now-defunct Indonesian Restructuring Agency (IBRA), freeing him from paying the debt.

Syafruddin has also been named as a suspect in the case.

The Attorney General’s Office (AGO) initially launched a probe into Sjamsul for allegedly misusing the fund, but decided to drop the case in 2008. In 2013, AGO successfully brought home former Bank Surya general director Adrian Kiki Ariawan from Australia, another suspect in the BLBI case. He was brought back via an extradition agreement with the Australian government.

“But we do not have an extradition agreement with Singapore. So the only possible way is by using Interpol's network,” Prasetyo said. (Saf)
