The mystery of what happened to Malaysia Airlines Flight MH370 continues to deepen, with claims of a past cockpit security breach by one of the pilots cropping up now and adding to the theories floating. An Australian news programme had mentioned about the security breach involving the co-pilot of the airline.

The claim came as military data revealed the missing plane had changed course and made it to the Malacca Strait—hundreds of kilometres from the last position recorded by civilian authorities.

Adding another question mark to the flight’s disappearance was the allegation by the Channel Nine network that the First Officer Fariq Abdul Hamid, 27, had, along with another pilot, violated airline rules in 2011 by allowing two young South African women into their cockpit during a flight.

The report included photos of the women in the cockpit, with one appearing to show them posing with a man resembling Fariq. It is claimed the breach took place during a one-hour flight from the Thai beach resort of Phuket to Kuala Lumpur, Malaysia’s capital.

“Malaysia Airlines has become aware of the allegations being made against First Officer Fariq Abdul Hamid which we take very seriously. We are shocked by these allegations,” a statement by the airline said.

“We have not been able to confirm the validity of the pictures and videos of the alleged incident. As you are aware, we are in the midst of a crisis, and we do not want our attention to be diverted,” the airline said.
