This was confirmed by the joint operations commander Colonel Esekia Wenzel, who says the men were detained but then released without being charged.
Colonel Wenzel could not verify the circumstances surrounding the detainment but says his office has confirmed that the men were detained following a tip off to police.
These three men, attached with the Air Transport Wing, are currently on leave from duties.
One of them was en route to Kavieng for an emergency leave but was detained along with the rest of the men, who were all in the same group travelling into Kokopo.
The other two are understood to be attached in employment with the S.O.S security firm on leave employment.
Circumstances surrounding the detainment of the men have yet to be clarified by the Kokopo police.
