At least 51 were arrested as part of a smuggling operation from Tokyo to Korea
The male smugglers hid as many as six gold bars in their rectums over one trip
Meanwhile the women smugglers hid the bars, weighing 200g, in their vaginas
Value of gold confiscated by the police was highest in a single smuggling case
At least 51 people including several housewives were arrested at Incheon International Airport early last month, the Korea Times reports.
The smuggling happened from March 2015 and the gold came from Tokyo and China's Yantai.
Korea's gold price is reported to be higher than other countries because of the 15 per cent tax imposed on the metal.
'Gold smuggling is a business people can make money easily from because of the price gap,' an official at the Korea Customs Service (KCS) has said.
'As our crackdown gets tougher, smugglers are also getting more sophisticated in hiding gold or other jewelry products they want to bring in.'
This is not the first time this has happened....the video below reflects a similar crime from 3 years ago.
