Police helping with the search for missing Malaysia Airlines flight MH370 have searched the home of its pilot, after investigators revealed "deliberate action" was taken on board the airliner to alter its direction.
During a dramatic press conference this morning, Malaysian Prime Minsiter Najib Razak said they now believe someone deliberately shut off the jet's communications and tracking systems, turned the plane around and flew for almost seven hours after it vanished.
Shortly after he finished speaking, a police source said officers had arrived at the home of 53-year-old pilot Zaharie Ahmad Shah, to search for evidence that could help with the investigation.
Investigators are increasingly focused on the possibility the plane was flown off-course by the pilot or co-pilot, or someone else on board with detailed knowledge of how to fly and navigate a large commercial aircraft.
Najib also revealed this morning that new data showed the last communication between the missing plane and satellites was at 8.11am Malaysian time - almost seven hours after it dropped off civilian air traffic control screens at 1.22am last Saturday.
It was flying across the mouth of the Gulf of Thailand on the eastern side of Malaysia, towards Vietnam.
Najib said satellite data confirmed that an unidentified aircraft which later appeared on military radar off Malaysia's west coast before going out of range at 2.15am was flight MH370.
He said: "Up until that point at which it left military primary radar coverage, these movements are consistent with deliberate action by someone on the plane."
Analysis of this new information means they are now focusing the search on two corridors; one to the north, which stretches from Thailand to the border of Kazakhstan and Turkmenistan, and the other to the south from Indonesia to the southern Indian Ocean
