Jakarta. Prosecutors investigating the graft scandal involving businessman Harvey Moeis have expanded their probe to his actress wife, Sandra Dewi, to determine if she also received any ill-gotten money.

Earlier on Wednesday, the Attorney General’s Office said that Sandra’s personal assistant had been interrogated by prosecutors to ascertain Sandra’s earnings from her own jobs.

Harvey is accused of illegal tin mining within the mining areas of the state-owned tin miner Timah, causing an estimated loss of Rp 300 trillion ($18.5 billion), mostly in environmental damages.

Since his detention two months ago, prosecutors have attempted to seize his personal assets. However, complications arose after his attorneys claimed that Harvey and his wife have a prenuptial agreement on the separation of their assets.

The attorneys warned that prosecutors cannot seize assets belonging to the well-paid actress.

"We have already interrogated the personal assistant to determine Sandra Dewi’s revenue sources and the total amount of her earnings,” said Kuntadi, the criminal investigation director at the AGO.

He confirmed that prosecutors have frozen bank accounts belonging to the couple.

“Those accounts remain frozen pending the investigation as we trace the flow of the money,” Kuntadi said.

Prosecutors have named 22 suspects in the case, including Bambang Gatot Ariyono, the former director general of minerals and mining at the Energy and Mineral Resources Ministry.
