Malaysia's transport minister Thursday vowed to take stern action against an air traffic control supervisor if it is confirmed that he was asleep on the job when Malaysian Airlines Flight 370 disappeared a year ago, The Associated Press reported. 

An interim investigation report last Sunday contained transcripts of conversations between air traffic controllers in the region and the airline that revealed confusion in the hours after the Boeing 777 dropped off radar with 239 people aboard while flying from Kuala Lumpur to Beijing.

In one conversation four hours after the plane disappeared, a Kuala Lumpur air traffic controller told a Malaysia Airlines official that he would need to wake up his supervisor when pressed on the exact time of the last contact with the plane. The controller came on duty after the plane vanished.

Transport Minister Liow Tiong Lai said his department viewed the matter seriously and was conducting an internal probe.

"The work is on rotation. ... If he is on a working shift, this is serious. We will definitely take action if there is any misconduct," he told reporters.

Liow said the ministry didn't investigate the matter earlier as they were waiting for Sunday's report by the independent safety investigation team.

The ministry's probe will be "very fast," he added, without saying when it would be completed.
