There was chaos and panic at a 7-Eleven store in Thailand when a giant monitor lizard walked in and climbed store shelves.

In a video which has gone viral, people can be heard screaming and laughing in the background as the lizard reaches the top of a shelf.

The incident occurred in Nakhon Pathom, a town just outside Bangkok, according to video news website Newsflare.

A store employee called the police who then brought reptile handlers to catch the Godzilla-esque creature.

The handlers dragged the lizard out of the store and lured it towards a nearby brush.
