Dozens of South Koreans were arrested for smuggling gold in their private parts over a two year period, local media reports.
The smugglers are said to have sneaked in more than two tonnes of the precious metal worth around £77 million ($141m) since March 2015.
Male smugglers hid as many as six gold bars weighing 200g in their rectums while women stashed it in their vaginas.
At least 51 people including several housewives were arrested at Incheon International Airport early last month, the Daily Mail reports.
The value of the gold confiscated by the police was the highest in a single smuggling case.
