Bengal tigers are an endangered species. There's only about 6,000 of them left in the wild.
It's because they're so rare that there's a lot of money to be made from selling the skins.
Big profit for poachers
The skin trade is big business in China. The pelts are sold for decorating walls and floors and collars on coats.
Police are trying to crack down on this crime. But it's difficult to do when the demand is there and poachers stand to make so much money out of it.
