Acting Police Commissioner, Raphael Haufolo, says aviation authorities must consider the use of air marshals in all international flights for security reasons.
He expressed this following an incident last week in an Air Niugini international flight to Singapore.
Mr Haufolo said the seriousness of this incident warrants the need for all relevant government agencies to put in place measures to prevent such an incident from occurring again.
Mr Huafolo concerns follows the complaint from Lae-based businessman, Mathew Minape, who restrained a fellow passenger from opening an emergency exit door after inflating his life jacket while the plane was in flight early this month.
PX 392 was bound for Singapore when the incident happened over Indonesian airspace. Minape has not ruled out the possibility of a plane hijack, but says the fellow passenger was deliberate in his actions, but failed.
Motives behind the act carried out by the passenger, are still unknown.
Meanwhile, Air Niugini stated that the matter was reported to authorities in Singapore with PNG authorities also investigating the incident.
Air Niugini maintains that at no time was the safety of its passengers and crew at risk.
The matter was reported to authorities in Singapore with PNG authorities also investigating the incident.
