Thai airport authorities have arrested a local woman on suspicion of trying to smuggle a baby tiger cub in a suitcase to Iran.
Last Sunday, officials at Bangkok's international airport declared the suitcase of the 31-year-old woman to be overweight and subjected it to an X-ray examination which showed the tiger cub inside.
The cub, estimated to be about 3 months old, had been drugged with a large amount of sedative. It was taken to a wildlife conservation center in the capital.
On Friday, 5 days after the discovery, the cub was still unsteady on its feet, spending most of the time sleeping or otherwise feeding on milk.
An airport official said it was a shock to see an animal treated like that. The official also said that had the animal gone through hours of air travel, its chances of survival would have been slim.
Illegal trade in wild animals is described as rampant on black markets in Iran, where it is popular to have exotic pets.
Thai conservationists are calling for tougher punishment for poachers and smugglers.
