Five people in Indonesia have been arrested for poaching after authorities found the skin of a protected Sumatran tiger and four foetuses in a jar. Sumatran tigers are critically endangered, with fewer than 400 believed to be left in the wild. It's not clear if the foetuses were taken from the adult tiger whose skin was taken. Tiger cubs are born blind and are totally dependent on their mother for the first few months of their lives. An official from the Environment and Forestry Ministry said the suspects, from Riau province, were arrested after police received a tip-off. Two suspects are believed to have been acting as sellers. They face a maximum of five years in prison and a fine of 100 million rupiah ($7100; ￡5403).
