Transport Minister Liow Tiong Lai today dismissed speculations of possible suicide by MH370 pilot Captain Zaharie Ahmad, based on initial investigations by the US Federal Bureau of Investigation (FBI).

Liow said that Zaharie's flight simulator records, from about one week before the Malaysia Airlines flight en route to Beijing was reported missing, was not a proof that he had committed suicide by plunging the plane somewhere in the Indian Ocean.

"It (flight simulator) is not evidence that he (Zaharie) had flown the plane using the same route.

"Investigations are still ongoing and we leave it to the authorities to investigate any evidence that they have," Liow told reporters during a press conference in Putrajaya.

On Monday, news.com.au reported that FBI investigations found that Zaharie had flown his flight simulator in the direction of the location where MH370 is believed to have gone missing.

The report also stated that Zaharie is believed to have committed suicide by crashing the plane.

Liow also urged any parties with evidence related to the case to hand it over to the investigation authorities.

Malaysia, China and Australia had in a joint statement last Friday announced that the search for MH370 will be suspended if it was not found at the current location.

The flight with 239 passengers and crew had disappeared in March, 2014, and about US$$135 million had been spent on an underwater search spanning about 120,000 sq km of the Indian Ocean.
