The police commander in Papua New Guinea's capital city has urged local business houses to ask for police help to provide security when they need to transport large sums of money.
The NCD Metropolitan police commander Andy Bawa says that businesses should be vigilant in becoming fully aware of the credibility of any company they contract to provide security.
This follows a daring robbery in which over US$2 million was stolen from an armoured security van.
Police are investigating allegations a security guard with the company G4S disarmed fellow guards as they were transporting the cash between banks last week in Port Moresby.
The Post Courier reports that the cash, belonging to May Bank, was on its way to the Bank of PNG for banking when the heist occurred.
G4S security guards allegedly held up their escort commander and drivers and commandeered the armoured vehicle across the city to waiting cars, where they unloaded the cash and escaped.
Mr Bawa says some of the G4S guards have been detained and questioned.
He says he's confident of closing in on the suspects.
