A truck full of deadly cobras worth an estimated £10,000 was seized by Thai Customs officials after it was suspected that the haul had been illegally smuggled over the border with Malaysia.
Approximately 600 snakes were discovered on Monday night at a checkpoint in Pranburi, about 230km south of Bangkok, and it is believed they were heading north towards the border with Laos.
The cobras were packed into mesh bags inside around 100 plastic baskets for the journey and it is thought they were being shipped for use in traditional medicine or food in another country.
The Bureau of Investigation and Suppression had been tracking the case for a year, head of Thai customs Benja Louichareon said.
The driver was later arrested and the snakes that survived the ordeal will now be released into the wild.
