The Malaysian police is investigating people who handled a cargo of mangosteens being carried by the MH370 plane.
Officers, who claimed to have 'some clues', said nothing was being left to chance in the investigation.
It is understood officers are investigating the possibility that the cargo couldhave been sued to hide an explosive device.
According to express.co.uk, the exotic fruit was being carried in the hold of the Boeing 777.
Inspector-General Tan Sir Khalid Abu Bakar, leading the probe, said the cargo itself was now under investigation, but refused to reveal what clues had been discovered, the report added.
