The Malaysian Anti-Corruption Commission (MACC) will question Prime Minister Najib Abdul Razak regarding the RM2.6 billion donation he received.
"MACC would also ask Najib to give an explanation to the MACC about the donation he received," said the commission in a statement today.
The commission said it had already questioned the donor, who is a Middle-Eastern .
However, MACC could not reveal his identity and re-iterated that the donation had no links to 1MDB funds.
The statement was aimed at further clarifying its previous statement on Monday that said the large sum of money deposited into Najib's personal account was a donation.
"MACC found that many people are not clear and confused by assuming MACC had ended its investigation on SRC International or the RM2.6 billion.
"Talks have also been held with the attorney-general, who asked MACC to give an explanation on the (donations) while the investigation is still ongoing.
"MACC would like to stress that it had never said the case was closed. MACC has only said that the money was not from 1MDB," said the commission.
The commission hopes with this explanation, it would be given space to conduct its probe comprehensively without having to deal with speculation.
"As an independent commission, MACC is responsible for carrying out its investigation independently, transparently, and professionally, without fear or favour.
"MACC would not allow any party to influence or interfere with the investigations," it said
The statement was not signed by any official. MACC chief Abu Kassim Mohamed is currently on leave while his deputy Mohd Shukri Abdull is abroad.
