A private land and sea survey corporation says it has noticed possible material from the lost Malaysian jetliner in the Bay of Bengal.
The site identified by GeoResonance is thousands of kilometres from the present search area off the southwest Australian coast.
Malaysian Defence Minister Hishammuddin Hussein said experts are working to verify the Australia-based company's claim.
On the other hand, the Australian agency organizing the multinational search lay off the report, saying it is "satisfied" with its present search location.
Private detective dogged the current search area using satellite data and what they trust are signals from the plane's flight data recorder.
GeoResonance used imaging and radiation technology to search the ocean floor for resources such as aluminium, titanium and jet fuel, which belong to a Boeing 777.
The corporation says it is not ready to state that the material it situated belongs to the missing jet, but says it wants the answers to be examined.
The Malaysian Airlines flight was carrying 239 travellers when it vanished on March 8 during a flight from Kuala Lumpur to Beijing.
The Malaysian government trusts someone with aeronautics knowledge deliberately diverted the plane, but a study has turned up no solid leads.
A huge search linking dozens of aircraft, ships, sonar listening devices, and a robotic undersea has also failed to locate the plane.
The hunt is now focused at the bottom of the sea; after establishments acknowledged there is little chance that any floating debris will be found.
