In a statement, Tan said MACC confirmed that the investigation had been completed and classified as requiring “no further action”, or NFA.

He welcomed MACC’s decision, pointing out that he had consistently maintained his innocence throughout the probe.

“The investigations and publicity given thereof have caused me severe reputational damage and undone what has been a lifetime of public and corporate service, causing immense strain on my family, friends, and the organisations I serve.

“I am grateful to all of them, especially my wife, family and dear friends, for standing by me. I now want to put this difficult period behind me and move on,” said Tan.

Separately, IJM said MACC had confirmed that no further action would be taken in relation to investigations into Sunway Bhd’s takeover bid.

“IJM welcomes the conclusion of this matter. The company has cooperated fully with MACC throughout the process and remains committed to supporting the authorities as required.”

The company also reiterated that MACC had previously confirmed the investigation did not involve IJM as an entity.

“With this matter now concluded, IJM moves forward with resolve, focussed on executing its strategic priorities, and unlocking the value of its portfolio across the group’s core businesses,” it said.

On Feb 6, MACC detained Tan as part of an investigation into alleged corporate governance issues, procurement processes, financial transactions, and overseas asset ownership involving an estimated value of RM2.5 billion.

According to now-former MACC chief commissioner Azam Baki, the UK’s Serious Fraud Office was also investigating IJM.

MACC raided various locations in its investigation, including Tan’s home and IJM’s offices, and also froze bank accounts involving about RM15.8 million.
