Mr Muhyiddin, the Perikatan Nasional chairman, has already recorded his statement over the same investigation, Bernama reported.
Mr Muhyiddin has since said that he was not a suspect in the investigations.
He was quoted as saying by Free Malaysia Today (FMT) that he was called in by the anti-graft agency to explain certain issues related to the Jana Wibawa project.
“I was called in specifically (to answer questions) about Jana Wibawa. Not (for an investigation into) RM600 billion, RM530 billion, RM86 billion or RM4.5 billion,” Mr Muhyiddin was quoted as saying by FMT.
Mr Azam, the MACC chief, however, has hit out against Mr Muhyiddin’s remarks, cautioning those called up for questioning to refrain from commenting on the issue.
“Investigations are ongoing and it is inappropriate to draw their own conclusions, regardless if they are called in as witnesses or suspects,” Mr Azam was quoted as saying by Bernama.
