Vietnamese environmental police stopped a taxi Friday carrying four suspected wildlife smugglers and confiscated two frozen tiger carcasses hidden in the trunk, according to dpa. The tigers were an adult and a cub, said Doug Hendrie, a wildlife crime technical adviser with the organization Education for Nature Vietnam. Two of the suspected smugglers came from Hanoi, while the others were from provinces further south. The suspects reportedly told police they had been commissioned by a third party to obtain the tigers. Exploiting tiger carcasses is illegal in Vietnam, but the meat is prized as a delicacy. Tiger bones are often boiled down into glue and used as an ingredient in traditional medical remedies.
