The Malaysian Anti-Corruption Commission (MACC) is mulling to increase campaigns to encourage whistleblowers to report on cases involving bribery and corruption.

MACC chief commissioner Dzulkifli Ahmad also vowed that the identities of whistleblowers and informants would be protected, in line with provisions of the Whistleblower Protection Act and the Witness Protection Act.

He was responding to the perceived reluctance of civil servants to report bribes despite the existence of cash incentives.

Since the scheme was introduced in 2011, less than one percent of over a million members of the civil service have been awarded the incentives.

Commenting on the matter, Dzulkifli said some may have rejected the bribes outright and decided not to report the matter.

"Another reason could be that they did inform us but did not lodge a report. Maybe he or she reported it but do not want the reward.

"There are many reasons. It's not because they accept bribes and keep quiet about it," he said at a press conference in Kuala Lumpur today.

Asked whether the reluctance could be due to fear of having their identities blown, Dzulkifli said such a possibility does not arise.

"Because, under the law, the information will be protected and we will protect their identities, we won't leak them.

"There is the Witness Protection Act and the Whistleblowers Protection Act. InsyaAllah, maybe we need to have more campaigns to let the rakyat know about their rights under these Acts," he said.

Dzulkifli had earlier launched Majlis Amanah Rakyat (Mara) and MACC's collaboration in the Gerakan Revolusi Anti Rasuah (Gerah) and the 3J - Jangan hulur, Jangan kawtim, Jangan settle - (don't give and don't settle) campaigns.

Three Mara Liner buses will be displaying the respective messages of the two campaigns for a year.

Former top civil servants and the head of an anti-corruption NGO had expressed their opinion that the MACC must look into the reasons behind the reluctance of civil servants in reporting bribes.

They suggested that MACC's apparent lack of credibility may be a reason behind the reluctance of civil servants reporting bribes.

Sabah MACC director Sazali Salbi said last week that civil servants who report corruption cases to MACC will receive a reward in the form of cash incentives with the same value of the bribe involved.
