Rosmah Mansor, the wife of former Malaysian prime minister Najib Razak, was arrested on Wednesday for allegedly receiving and transferring funds related to money-laundering activities.

The 66-year-old former first lady of Malaysia was detained this afternoon at the Malaysian Anti-Corruption Commission (MACC) headquarters in Putrajaya, after more than four hours of questioning.  Malaysiakini reported that Rosmah is expected to be charged on Thursday.

“She will face charges under the Anti-Money Laundering, Anti-Terrorism Financing and Proceeds of Unlawful Activities Act (Amla),”  MACC deputy commissioner Azam Baki told Malaysiakini.

She was interrogated on Wednesday for the third time as part of its probe into SRC International, a former subsidiary of state fund 1Malaysia Development Berhad (1MDB) which has been at the centre of investigations by several countries for alleged misappropriation of billions of dollars.
