Graft remains rampant in the archipelago nation, which ranked 110th out of 180 nations in Transparency International’s latest corruption perception index.

Former agriculture minister Syahrul Yasin Limpo resigned last week because of the allegations levelled at him, and the corruption eradication commission (KPK) formally named him as a suspect on Wednesday.

He was detained yesterday, with local media showing him being taken handcuffed into the commission’s offices in the capital Jakarta.

KPK spokesman Ali Fikri would not confirm if the commission had arrested Limpo on formal charges, but he told reporters yesterday evening that the commission detained him because of concerns he would flee or destroy evidence.

He said KPK investigators were still questioning Limpo today.

“It is still ongoing. We will update … this afternoon,” Fikri told AFP today.

Fikri said Limpo missed the commission’s summons on Wednesday for questioning, citing family reasons.

He is the sixth minister to be investigated for corruption since President Joko Widodo took office in 2014.

The Indonesian leader told reporters today that “there must be reasons” for Limpo’s arrest.

“Let us respect the legal proceedings,” he said, according to state news agency Antara.

Limpo’s lawyer Febri Diansyah did not immediately respond to an AFP request for comment.

But he told reporters late yesterday the former minister “would not run away”.

Limpo is accused of forcing ministry officials to send him money from state coffers every month, using the cash to pay for credit card bills and instalments on a luxury car.

He is also accused of bribery and abuse of power “to enrich oneself or others” according to Indonesia’s anti-corruption law, the KPK said Wednesday.
