Investigators are reportedly looking into the possibility that the passengers of the missing Malaysian Airline jet are being held hostage at an unknown location.
The ill-fated Malaysian Airline Flight 370 took off from Kuala Lumpur on Saturday and after just 40 minutes went off radar and it is yet to be found.
An American journal published the claims that counterterrorism officials now believe that someone on board deliberately turned off the plane's transponders to avoid radar detection, news.com.au reports.
It has been claimed that the jet maintained contact with the satellites and stayed in air for a total of five hours after it went off radar.
The journal stated that the investigators were actively pursuing the notion that the plane was diverted 'with the intention of using it later for another purpose.'
