JAKARTA (Yosefardi) – The Corruption Eradication Commission (KPK) has summoned Commissioner of state oil & gas company PT Pertamina Sahala Lumban Gaol for questioning session on Monday (May. 25) related to investigation into bribery case implicating Innospec Ltd.

KPK’s Spokesperson Priharsa Nugraha said Sahala will be questioned as a witness for Suroso Atmo Martoyo, former Pertamina’s Director for Processing and one of suspects in the case.

Sahala is also listed as expert staff at the Ministry of State-Owned Enterprises (SOE’s).

As reported earlier, KPK had named Suroso Atmo Martoyo and Willy Sebastian Liem (Director of PT Soegih Interjaya) as suspects in the case back in 2011 and 2012. Both suspects, however, have just been detained in February 2015.

Innospec, a chemical supplier for state oil and gas company PT Pertamina, was alleged for bribing Indonesian officers in the period of 2002-2006 in order to secure sales of tetraethyl lead (TEL), an additive used in the production of unleaded gasoline. (haryantosuharman@yosefardi.com)
