The report added gendarmerie officers recovered it for "the purposes of the investigation" on the mysterious missing of the MH370 flight.

The flight, a Boeing 777-200, was reported missing en route from Kuala Lumpur to Beijing on March 8, 2014, with a total of 239 passengers on board, most of them Chinese.

So far, the plane has not been found despite a massive surface and underwater hunt, which has become one of the biggest mysteries in the aviation history.
