Tiger organs and bones are used for medicinal purposes in the communist country, where a thriving local market drives the illegal sale of animal parts including ivory and rhino horn. But Vietnam is also a key transit route for wildlife parts destined for elsewhere in Asia , including neighbouring China.
"The authorities found inside a freezer five dead tigers, with the skins intact but the internal organs removed," it said.
The tigers were Indochinese, according to Vietnam News Agency, but officials said police would investigate further.
Police refused to comment.
