Terrified bank staff found a live snake in the toilet in Thailand.

Shocked workers called the emergency services when the 6ft long rat snake was seen slithering across the tiles of the restroom at a branch of the Krungthai bank.

Reptile handlers arrived to catch the serpent inside the financial facility in Nakhon Si Thammarat province on December 22.

They said it had taken them around 20 metres to catch the non-venomous snake, which was around two-metres long when they measured it.

A Krungthai employee said that they were shocked when the opened the door and saw the large snake on the ground next to the toilet.

The snake was captured and released into the wild, to the relief of the employees and customers at the bank.
