Police have made conflicting remarks on whether they will investigate a report lodged by an aide to former prime minister Najib Abdul Razak on DAP veteran Lim Kit Siang's claims regarding several high-profile murders.

Sentul district police chief S Shanmugamoorthy Chinniah had previously told Malaysiakini there was nothing to investigate as it was a civil matter.

However, inspector-general of police Fuzi Harun (above) at an event in Johor today said that a probe will be initiated.

"The report was lodged at the Sentul (district police headquarters) by Najib’s aide against certain politicians with regard to their allegations (against Najib).

“So we will investigate and take appropriate action. This is a normal process,” Fuzi was quoted as saying by Bernama.

He added police will also call up the politicians involved if necessary.

Yesterday, Malaysiakini had sighted the report filed by the aide at the Sri Hartamas police station.

The complainant urged the police to investigate Lim based on a Malaysiakini article where the latter said he would reopen investigations into the deaths of Altantunya Shaariibuu, Kevin Morais, Hussain Najadi, Teoh Beng Hock and Ahmad Sarbani Mohamed if he were prime minister.

On Thursday, Najib had said he would instruct an aide to file a police report against him so the authorities can investigate if he was involved in the murders.

The former premier said this would be the last resort for him to clear his name.
