A terrified boy alerted his mum after spotting a snake slithering on their sofa.

Four-year-old Nong was playing inside their bedroom when he saw the 1ft-long (30 cm) serpent on their pink furniture in Bangkok, Thailand on June 11.

He was shouting while telling his mother who then pulled the boy away from the sofa.

Footage shows the scared youngster pointing to the spot where the snake had been hiding inside their home.

Mother Chananchida Adulyarithiku said: ‘I was cleaning the room when he suddenly shouted. I could have been bitten if he didn't alert me about the snake.'

The family went out of the house and called the animal rescuers for help who caught the snake.

No one was hurt in the incident while the snake was released back into the wild.
