Police in central Vietnam on Monday seized a 120-kg frozen tiger carcass in a "suspicious" truck heading north on National Route 1A in Nghe An Province.
The truck driver Nguyen Van Lap claimed that a "stranger" had paid him VND8 million to transport the carcass to the north.
Police say further investigations are ongoing.
In Vietnam, products made of tigers, including tiger bone paste, are believed to have medicinal value.
It is illegal to hunt, kill, trade or advertise tigers or tiger products in the country.
