DHAKA: Malaysia police are looking into possible pilot suicide in their investigation into missing Malaysia Airlines flight MH370, as it emerged that the last message from the cockpit, believed to be from co-pilot Fariq Abdul Hamid, came around the time that two of the plane’s crucial signalling systems were manually disabled.

But acting Malaysia transport minister Hishammuddin Hussein, speaking at a daily press briefing on Monday, declined to say if anyone on board the flight had personal problems, reports The Straits Times.

Uncertainty also deepened over when the Aircraft Communications Addressing and Reporting System in the missing jetliner could have been switched off. ACARS transmits key information on a plane’s condition to the ground.

MAS CEO Ahmad Jauhari Yahya, speaking at the same briefing, said the last ACARS transmission was at 1.07am and the last pilot communication was at 1.19am.
