Two children have been taken hostage in what Papua New Guinea police say is an alarming new wave of kidnappings and robberies, some achieved with inside help.
PNG's Post-Courier newspaper says the children of a Port Moresby jeweller, aged seven and 12, were kidnapped by armed criminals on Friday morning after being dropped off at school.
The kidnappers then demanded 100,000 US dollars in cash, gold and jewellery in exchange for their return.
Port Moresby police say the children were rescued within an hour of being snatched and two kidnappers were arrested.
Police are investigating whether the kidnappers had inside help.
Last month, a bank manager's family was taken hostage in Port Moresby while other gang members forced him to hand over nearly 400,000 US dollars from his Bank South Pacific branch at Kerema, about 400 kilometres away.
Police have arrested several bank staff over their role in the robbery.
