Up to a hundred and eighty armed renegade police officers in Papua New Guinea are threatening to storm the capital unless their pay demands are met.
The officers have sealed themselves off in the Bomana police training college outside Port Moresby in a protest, demanding special pay allowances for security provision at last week's Forum leaders' summit.
The president of the PNG police association, Robert Ali, says the police management hope to resolve the standoff peacefully and quickly.
Sergeant Ali says the union supports the fair pay demand but not the method of protest.
"There's already some serious concerns raised... the cause to which they are pursuing is genuine, and it's just the action and the process to which they've brought about their grievances is a matter that the union is not happy about."
Mr Ali says the officers were issued with a range of firearms for operational purposes.
