As the search for the plane entered the 12th day with no significant progress so far, Defence and Transport Minister Hishammuddin Hussein told reporters that some data from simulator was deleted on February 3 and investigators are trying to recover the missing files.
He also said that the 53-year-old pilot, Captain Zaharie Ahmad Shah, and all passengers remained innocent until proven guilty of any wrongdoing.
According to some reports, investigators found the runways with over 1,000 metres length of five airports, including three in India and Sri Lanka, one at the Male in Maldives and an airport owned by the US (Diego Garcia), loaded into the home-made flight simulator of Captain Zaharie.
Captain Zaharie and first officer of the missing plane, both Malaysian, have come under scrutiny in the search for clues to trace the Beijing-bound Boeing 777-200.
Hishammuddin said, "We have received passenger background checks from all countries apart from Ukraine and Russia, both of which had nationals on board. So far, no information of significance on any passengers has been found."
He dismissed reports that the plane had been seen over the Maldives. "This is not true," he said adding he spoke to Maldivian officials on the matter.
Hishammuddin said that Malaysia has received some new radar data, but would not reveal where it came from.
Thailand yesterday said its radar confirmed that a plane took a westerly turn on March 8. Hishammudin said the source of the data was sensitive and that it was up to the host country to release it.
Some reports said Malaysian officials also reviewed cockpit conversations between the pilots on board the missing plane and air traffic controllers and heard nothing suspicious.
