Other Indian Ocean islands near French-owned Reunion are being asked to look out for more possible debris after a wing part suspected of being from missing flight MH370 came ashore.
The Malaysia Airlines Boeing 777, carrying 239 people, vanished in March 2014 when flying from Kuala Lumpur to Beijing.
The wing part discovered on Wednesday has been taken to mainland France for tests. But other items found at the weekend were not from an aircraft.
Malaysia’s director general of Civil Aviation Azharuddin Abdul Rahman told Associated Press: “I read all over media [the new debris] was part of a door.
“But I checked with the Civil Aviation Authority, and people on the ground in Reunion, and it was just a domestic ladder.”
The Agence France-Presse news agency said on Sunday that one of its photographers had also seen a mangled piece of metal inscribed with two Chinese characters, attached to a leather-covered handle and measuring 100 sq cm being placed into an iron case and carried away.
But some social media commentators suggested it might be a kettle. A source close to the inquiry told AFP that “no object or debris likely to come from a plane” had been submitted as evidence on Sunday.
