A hunt for more wreckage from missing flight MH370 on La Reunion island has turned up no new clues as authorities said metallic debris found by locals did not come from an aeroplane.

Reunion locals have been combing the shores since a Boeing 777 wing part was found last Wednesday, sparking speculation that it may be the first tangible evidence that the Malaysia Airlines plane crashed into the Indian Ocean.

Over the weekend, at least two metal objects were found by locals and handed to police, none of which were found to be related to a Boeing 777.

“People are more vigilant. They are going to think any metallic object they find on the beach is from flight MH370, but there are objects all along the coast, the ocean continually throws them up,” said Jean-Yves Sambimanan, spokesman for the town of Saint-Andre where the wing debris was found.

Malaysian Transport Minister Liow Tiong Lai said civil aviation authorities have asked their Indian Ocean counterparts to lookout for further debris.

He confirmed that the wing part found Wednesday on the French island had been “officially identified” as from a Boeing 777, making it virtually certain that it was from missing Malaysia Airlines flight MH370. Flight MH370 is the only Boeing 777 to ever be lost at sea.

A spokesman for Australia’s Transport and Infrastructure Minister Warren Truss said more “objects are being brought to local stations but nothing ‘obvious’ so far. And no door.”

Australian search authorities leading the hunt for the aircraft some 4,000km from Reunion are confident the main debris field is in the current search area.

The discovery has been yet another painful twist for the families of the victims

This comes as Malaysian authorities confirmed on Saturday that an aircraft wing washed up on the same Indian Ocean island was from a Boeing 777, which was the same plane as flight MH370.

The debris, part of a plane wing called a flaperon, could provide the first tangible clue to unlocking the mystery surrounding the doomed Malaysia Airlines plane, which disappeared without trace on March 8 last year with 239 people on board, including six Australians.

The two-metre segment was shipped late on Friday from Reunion, east of Madagascar, to the French city of Toulouse on Saturday.

If confirmed as being from the doomed Malaysia Airlines flight, the discovery would mark the first breakthrough in a case that has baffled aviation experts for 16 months.

The convoy containing the two-metre wing part was escorted by police from Paris to the defence ministry laboratory near the southwestern city of Toulouse, encased in a wooden crate.

The part was flown overnight to the mainland from the French island of La Reunion, where it was found on a beach in the town of Saint Andre earlier this week.

From Paris’ Orly airport, it was driven south by road, arriving at the laboratory at about 5.30pm on Saturday.

MH370 disappeared on March 8, 2014, en route from Kuala Lumpur to Beijing with 239 people on board, including six Australians.

Malaysian and French experts will on Wednesday begin their analysis of the part, as well as fragments of a suitcase discovered nearby.

Australia continues to shoulder most of the cost of searching for the vanished passenger jet, though China – which had 153 nationals aboard – is yet to contribute financially to the underwater search.

Malaysia has chipped in more than $46 million to the cost of combing 120,000 square kilometres of ocean.

A spokesman for Deputy Prime Minister Warren Truss said on Saturday funding talks between the three nations are continuing.
