KUALA LUMPUR - Inspector-General of Police Tan Sri Khalid Abu Bakar says investigations into the missing MH370 aircraft is so intricate that even a cargo of mangosteens on board has to be traced to its last detail.
The IGP said all 227 passengers on board the plane were cleared of any suspicion connected to the vanished aircraft after more than 170 statements had been recorded.
However, the 12 crew members were still being probed under four possible angles - hijacking, sabotage, psychological problems and personal problems.
Khalid pledged full transparency over the investigations, adding that all details were being probed, including the food served on board the missing Boeing 777-200.
"When we knew there was a load of mangosteens on board, we had to find out where the fruits came from," he said. "We tracked down to who plucked the fruits, who packed and shipped them out, and who put them on the plane.
"Then, we had to see who was to receive them in China and who paid for it, and how much.
"Imagine how many people we must interview to rule out sabotage. And, that is just for mangosteens," Khalid said, disclosing that the shipment of mangosteens came from an orchard in Muar. "To eradicate sabotage, we had to find out who prepared the food."
The IGP has also not written off the private flight simulator of MH370 pilot Capt Zaharie Ahmad Shah.
"The Malaysian police have not received any response from their foreign counterparts, including the US Federal Bureau of Investigations (FBI)," he said.
Acting Transport Minister Datuk Seri Hishammuddin Hussein said on Saturday that the FBI had found "nothing sinister" about the simulator.
