MACC sources were quoted by Astro Awani as saying that the move followed an investigation into the ownership of a house which was allegedly bought using 1MDB money.

He said Rohana was prohibited from doing any transaction involving her bank account in the United Kingdom.

The assets were frozen under the anti-money laundering law after MACC began an investigation into the allegations by former Goldman Sachs banker Tim Leissner who testified in a US court that she had demanded a house worth US$10 million in London.

Rohana in a statement on Friday confirmed that she was called to MACC headquarters in Putrajaya on Thursday for further investigation following the revelations related to 1MDB.

Leissner had testified that Rohana, with whom he had an affair for 10 years, had threatened to reveal the involvement in the 1MDB scandal.
