Jakarta. The Corruption Eradication Commission, or KPK, on Monday named the head of the Makassar Customs and Excise Office a suspect two months after he was first interrogated for alleged undeclared assets.

Andhi Pramono came under the spotlight for posting photos of luxurious vehicles on his social media accounts, prompting public inquiry into his lavish lifestyle as a state official in the South Sulawesi capital.

The Financial Transaction Report and Analysis Center, or PPATK, also revealed suspicious transactions tied to Andhi.

His criminal charges were confirmed by KPK spokesman Ali Fikri, who didn't mention a name when asked by reporters at his office in Jakarta.

"We have formally begun a criminal investigation into an official of the Customs and Excise Directorate of the Finance Ministry, and we have a suspect," Ali said.

When asked which official, he replied: "The one in Makassar". 

Andhi was summoned by the KPK in mid-March to clarify his wealth report. After the interrogation, journalists asked him about a luxury house in the Jakarta suburb of Cibubur that he had posted on his social media account.

He claimed that the house belongs to his parents. KPK investigators have launched a probe into the Cibubur house.

In his previous filing in February last year, Andhi mentioned that personal wealth worth Rp 13.7 billion ($891,000), comprising mostly lands and buildings.

He owns a house built on 513 square meters of land in Central Jakarta valued at Rp 4.9 billion. Andhi also has houses in Cianjur, Bogor, Salatiga, and Batam, according to his filing.

His assets also include nine cars and four motorcycles that according to his own valuation are worth Rp 1.8 billion.

Following the KPK announcement, a Finance Ministry spokesperson said Andhi was suspended from his post to support the ongoing investigation.

Andhi is the second Finance Ministry official to become a graft suspect in recent months after KPK implicated tax official Rafael Alun Trisambodo with money laundering and bribery charges in March.

Rafael has since been discharged by the Finance Ministry.
