A leaked document has revealed that Australian authorities are concerned that two Indonesian pilots may pose a security threat after being radicalized by ISIS.

The Australian Federal Police's "Operational Intelligence Report," published online by investigative website The Intercept, said the pilots were "likely employees" of AirAsia and Premiair and came to their attention through their Facebook pages.

The report touches on the behavior of the pilots on social media, which has led the AFP to believe that they pose potential security threats because of their knowledge of aviation and possible radicalization, according to NBC's South Carolina affiliate WYFF 4.

"Upon review of the content from both accounts it is assessed that these persons are likely being influenced by radical elements -- at least from the online environment --- and as a result, may pose a security threat," the document reads..

The federal police would not comment on whether the document, entitled "Identification of Indonesian pilots with possible extremist persuasions," dating back to March 18 this year, was genuine, CNN reported.

"The Australian Federal Police does not comment on matters of intelligence," they said to reporters.

A spokesman for Indonesia's Ministry of Foreign Affairs Arrmanatha Nasir said he had requested more information about the two pilots from Indonesia's security authorities.

"We are in coordination to find out more about how this case can be verified," he said

ISIS has had an increasing effect on people outside their usual sphere of influence as of late, as teens from Singapore were arrested earlier this year due to their links to  ISIS.
