MACC chief commissioner Azam Baki said the videos “lacked credibility”, Bernama reported.

“They cannot be used in our investigation and would also be inadmissible in court,” Azam was quoted as saying, adding that the videos had been handed to the police forensic unit.

The videos were published by a news portal and also widely shared on social media. Azam said MACC was considering calling up the portal to enquire how it obtained the videos.

Azam said MACC had recorded the statements of five witnesses, including a politician from Sabah in connection to the alleged scandal. He has previously said MACC had completed its investigation into the purported whistleblower and a former CEO of a company linked to the alleged scandal.

On Friday, Penang DAP deputy chairman Ramkarpal Singh contended that the leaked videos, implicating several assemblymen, had revealed enough information for MACC to invoke various measures under the law including the powers of search and seizure.

He took MACC to task for claiming that insufficient information was hampering the probe into the alleged scandal.

However, Azam said the purported whistleblower who had leaked the videos had yet to surrender any evidence. In November, Azam criticised the purported whistleblower for presenting the agency with only a 17-second audio recording which was not clear.
