Even as the missing Malaysia Airlines flight MH370 remains untraced, a man claims to have witnessed the aircraft plunging into the South China Sea.

Alif Fathi Abdul Hadi, 29, from Ketereh, in the Malaysian state of Kelantan, has lodged a report with the Malaysian Maritime Enforcement Agency (MMEA) over the claimed sighting of the aircraft as it was going down.

The businessman said he had seen a bright white light, similar to those used by planes during night flights, moving towards the sea at about 01:45am local time on the day the Beijing-bound Boeing 777 vanished.

Although he initially thought that there was nothing unusual, he went on to file the report with the authorities after hearing the news of the missing passenger jet with 239 people aboard.

"I was walking towards my back door when I caught a glimpse of the white light. It was moving towards the sea, towards Bachok area, which was unusual. Usually, aircraft that fly over here have their route pattern, but this one went completely towards the other way," Abdul Hadi told Malaysia's New Strait Times.

He, however, admitted he was not sure if the white light was actually from a plane, adding there were no blinking red lights.

"I did not think much about it, and went to sleep. Only the next day, when I heard the news on the radio, I thought that the light I saw could be from the aircraft. After discussing with my family members, they advised me to lodge a report, and I hope this information can be of any help."
