Riza Aziz, the stepson of former premier Najib Abdul Razak may return to MACC headquarters in Putrajaya for the fourth consecutive day tomorrow.
The graft-busters have been recording Riza's statements since Tuesday over allegations that 1MDB funds were channelled into his film production company, Red Granite Pictures.
He is currently being questioned by the MACC at its headquarters, after having arrived at 11am today.
"The MACC officers are expected to finish recording his statements about 9pm today, and if it's not enough, he will have to return to MACC at 10.30am tomorrow," said a source within MACC.
On Tuesday, Riza was grilled for nine hours.
Yesterday, he returned to the headquarters at 3pm, where he was questioned by the commission for another six hours.
The US Department of Justice (DOJ) has claimed that US$64 million in allegedly misappropriated 1MDB funds was wired to Red Granite and used to finance the production of several Hollywood movies – including Martin Scorsese’s 2013 film The Wolf of Wall Street.
The sum was part of US$238 million in allegedly stolen funds that the DOJ believes were transferred to accounts controlled by Riza.
The company maintains that it did not knowingly use stolen funds to finance its films.
Riza is also accused of using the funds to purchase luxury properties from businessperson Low Taek Jho.
According to the DOJ, he had also previously claimed that US$94 million of the 1MDB funds he received was "a gift."
