"As of tomorrow, I am no longer the CEO," he told a press conference on 19 August. "I have done my best, but I have evidently failed and therefore will be handing over my duties.
"I was told that some security measures were not followed by the sub-contractors and if that really is the case, I will make sure MRT Corp never works with them again."
He added that despite his departure from the company, he would see the case through and ensure that the families of the deceased are given justice.
MRT’s stakeholder relations and land management director Haris Fadzilah Hassan would take over until the Government appoints a new CEO.
