Malaysian Anti-Corruption Commission (MACC) adviser Tunku Abdul Aziz Tunku Ibrahim has denied dismissing a complaint about the prime minister's wealth when he said an investigation cannot be conducted on mere suspicion.

Abdul Aziz, who heads the Corruption Prevention Advisory Panel (LPPR), was referring to the report made by Kulai MP Teo Nie Ching to the MACC about Prime Minister Najib Abdul Razak's wealth.

"What I told reporters is that anyone can make a complaint to the MACC but the complaint must have evidence.

"If there are evidence, surely the MACC will conduct an investigation," he said in a statement today.

He added that Teo ( left ) should know the MACC had always conducted its investigations into cases which may contain elements of corruption fairly, independently, and professionally.

Teo in a statement earlier today had hit out at Abdul Aziz for stating that the MACC cannot kill a cat simply based on suspicion that the cat had stolen someone's fish.

"Rakyat of Malaysia never expects MACC 'to kill a cat merely because of the suspicion that the cat has eaten the fish'; we only demand MACC to investigate the cat.

"I believe Tunku Aziz should have no difficulties to understand the difference between investigation and actual punishment," said Teo.

Rebutting this, Abdul Aziz said he has 30 years of experience in anti-corruption and good governance.

He pointed out he had also urged anyone with evidence to go ahead and lodged a report.

In the press conference yesterday Tunku Abdul Aziz said Najib shuld be held accountable, but there must be evidence before any accusation can be levelled against him.

Teo today insisted there is evidence, as US-based New York Times which has highlighted Najib's wealth claimed to be in possession of documents showing million of dollars in jewellery was ordered by prime minister's wife Rosmah Mansor.
