Experts following the disappearance of MH370 say it is likely that a new piece of debris found on a Mozambique beach came from the missing plane, reports BBC.
Luca Kuhn von Burgsdorff contacted the BBC on Thursday to say he found the fragment on the Macaneta peninsula.
The authorities have been notified. The piece must be examined by the official investigation team in Australia.
Experts say it is consistent with where previous pieces of debris from the missing plane have been found.
Mr von Burgsdorff took two photographs of the item on 22 May, and sent them to the BBC after reading a story on Thursday about other debris finds in the region.
He said the pieces were "reasonably light, did not have metal on the outside, and looked extremely similar to photos posted on the internet of other pieces of debris from aeroplanes".
MH370, flying from Kuala Lumpur to Beijing, had 239 people on board when it vanished in March 2014.
It is presumed to have crashed into the southern Indian Ocean after veering off course.
