Azam said given the complexity of the case, which he described as “daylight robbery”, the anti-graft agency was meticulously vetting each and every one of the investigation papers.

His comment comes three days after PKR Youth deputy chief Kamil Munim called on the anti-graft agency to disclose the status of the probe.

Azam said to date, 51 people had been arrested, including 13 women.

It had been previously reported that the suspects comprised business owners, directors, managers, shareholders, engineers and executives.

Azam also said that following the probe into a cartel raking in profits by securing projects worth millions from the Shah Alam City Council (MBSA), MACC had arrested nine people, including senior MBSA officers.

On Sept 19, several MBSA staff were arrested, including a contractor believed to be involved in the multi-million ringgit Shah Alam Sustainable Urban Drainage Master Plan project.

Regarding the case involving the Malaysian Indian Transformation Unit, Azam revealed that another six people were expected to be charged for defrauding the government by making false claims to the tune of between RM900,000 and RM5 million.
