Last week, a Vietnamese wildlife trafficker has been busted selling tiger cubs. This isn't surprising - The New York Times reported last year that Vietnam, one of the most biodiverse countries has "thousands of illegal hunters".

However, it what he was doing to them that is shocking - the cubs were reportedly "frozen to make glue for its healing qualities", Daily Mail reported, The glue uses the tiger cub's meat, skin, claws and bone, and it is believed in oriental medicine that it has "healing qualities".

He was busted by Nam Dinh province police in Vietnam, and revealed that he'd bought the cubs from a Vietnam-Laos border market for VND2 million (£60). He planned to sell them for VND8 million (£250) - and was looking for a buyer on Facebook. Dr Pieter Kat, a scientist at LionAid, told the Express: 'There is no doubt that Vietnam's wild tiger populations have declined to perhaps a handful now surviving...However, there is also good evidence that Vietnam, like China is breeding tigers in captivity for the purposes of unfounded 'traditional medicines'.

Vietnam is infamous for its animal smuggling gangs. Just this month, India's Special Task Force (State Forest department) began work with Interpol to nab animal trafficking gangs in Vietnam)
