Bank Negara Malaysia took action against Ambank staff Cheah Tek Kuang and Joanna Yu over a 1MDB-linked case, the Finance Ministry said.

However, it did not specify what action was taken in the written parliamentary reply to Tony Pua (DAP-Petaling Jaya).

"Bank Negara investigated financial institutions involved in the 1MDB case under the Financial Services Act 2013, Islamic Financial Services Act 2013 and Anti Money-Laundering and Anti-Terrorism Financing Act 2001 and Proceeds of Unlawful Activities Act 2001.

"Based on the investigations, appropriate enforcement action was taken within Bank Negara's jurisdiction.

"Bank Negara was also allowed to share information with any enforcement agencies to assist in their investigations," stated the reply.
