A monitor lizard rampaged through a family's home and took a housewife by surprise in Thailand.

CCTV footage shows the reptile walking into resident Teenathad's garage in Ang Thong province on April 23.

The beast then sprinted toward the house, broke through the screen door, and ran past Teenathad's shocked wife.

A visitor later helped them get rid of the monitor lizard.

Asian water monitor lizards normally live in canals, swamps, sewers and ponds in cities in Thailand. They feed on fish, snakes, frogs and scraps of food left by humans.

The reptiles are aggressive when threatened and have a mildly venomous bite which sometimes carries harmful bacteria. The Godzilla-like reptiles are also a protected species in the country so their population thrives.
