While the islands' National Defence Force said that no trace of Flight MH370 had been picked up on radar, police and the civil aviation authority were investigating reported sightings on a remote island.
The investigations were sparked by a report by the Haveeru news website which said that several local residents had spotted a large plane flying over the remote southern island of Kuda Huvadhoo on March 8.
In a statement Wednesday, the Maldives National Defence Force (MNDF) said that studies of military radar had yielded nothing so far.
"Based on the monitoring up to date, no indication of flight MH370 has been observed on any military radars in the country," it said.
The civilian radars at the Maldives airports had also "been analysed" but there was no "indication of the said flight," the statement added.
The Maldives police and civil aviation authority separately confirmed that a more detailed national inquiry was underway and they were hopeful of giving a progress report later
