In 2010 at Bangkok International Airport, Thailand, a woman was stopped from boarding a plane to Iran when Customs officers became suspicious of her extra-large suitcase. They were in for a surprise when they finally got the chance to open it. Inside, lying beside a stuffed toy tiger was a REAL one! To keep it still and quiet, the 2-month-old cub had been heavily sedated. At first, the woman claimed the suitcase wasn't hers, but eventually admitted that, if she hadn't been caught, she would have sold the cub on the Iranian black market.
Not sure if the woman was fined or went to prison, but, for the tiger at least, the story has a happy ending: the cub was sent to a wildlife park where it can be properly cared for.
