This is probably an outcome many detractors had hoped to see.

Rosmah Mansor, the wife of former Malaysian Prime Minister Najib Razak, has been arrested on Oct. 3.

According to Malaysian news site Malaysiakini, the Malaysian Anti-Corruption Commission (MACC) confirmed that the arrest of the former first lady took place at 3.20pm.

The arrest took place at the MACC's headquarters in Putrajaya, where the 66-year-old had arrived earlier to record her statement.

This was her third time being brought in for questioning.

The first time being on June 5, regarding a probe into SRC International, a company that was previously a subsidiary of 1MDB.

Rosmah was then called in for a second time to undergo questioning with regards to 1MDB itself.

The questioning went on for 13 hours.

Charges

She will face charges under the Anti-Money Laundering, Anti-Terrorism Financing and Proceeds of Unlawful Activities Act.

According to The Straits Times, investigators believe funds from the aforementioned subsidiary may have possibly been used to fund the purchase of anti-ageing products from the United States that were hormone-based.

It is estimated to be worth RM$1 million, or S$332,000.

Cooperative

Earlier after her questioning in June, Rosmah's legal team said that she "gave her utmost cooperation during the process and was treated well by investigation officers".

They added that she will “extend further cooperation” as and when it is sought.

Rosmah has been in the spotlight quite a bit, mainly due to negative responses to her lavish lifestyle, such as her tendency to carry expensive handbags and items that have been uncovered in raids in residences linked to Najib.

Najib himself faces 32 charges, which include money laundering, abuse of power, and criminal breach of trust.

He has denied all of them.

Rosmah is most likely to be charged on Oct. 4 at the Sessions Court in Kuala Lumpur.

On the same day, Najib’s case has been set for case management.
