The last known position of MH370 was pinpointed as it headed east over the Peninsular Malaysia. Rada pings then suggest the plane could have then taken two paths along 'corridors' which are currently being searched. The northern corridor extends from northern Thailand to the Kazakstan-Turkmenistan border, while the south extends from Indonesia into the southern Indian Ocean.

Conclusion: Malaysian officials say flight MH370 could have been hijacked by one or several people with flying experience and deliberately diverted.

KUALA LUMPUR, Malaysia -- Malaysia's prime minister says the disappearance of Malaysia Airlines Flight 370 appears to be "deliberate."

Speaking to the press early Saturday, Prime Minister Najib Razak said the investigation has refocused onto the crew and passengers aboard the missing plane. He added that despite growing evidence to suggest a possible hijacking or sabotage, all possibilities are still being investigated.

The prime minister also said that authorities are now trying to trace the plane across two possible "corridors" -- a northern corridor from northern Thailand through to the border of Kazakstan and Turkmenistan, and a southern corridor from Indonesia to the southern Indian Ocean -- and that search efforts in the South China Sea would be ended.

"Clearly the search for MH370 has entered a new phase," he said.

Earlier, a Malaysian government official who is involved in the investigation said investigators have concluded that one of the pilots or someone else with flying experience hijacked the missing Malaysia Airlines jet.

The official said no motive has been established, and it is not yet clear where the plane was taken. The official spoke on condition of anonymity because he was not authorized to brief the media.

The official said that hijacking was no longer a theory. "It is conclusive."

The Boeing 777's communication with the ground was severed under one hour into a flight March 8 from Kuala Lumpur to Beijing with 239 aboard. Malaysian officials have said radar data suggest it may have turned back and crossed back over the Malaysian peninsula westward, after setting out toward the Chinese capital. CLICK HERE FOR MORE STORY»
