This is the dramatic moment a grandmother clung to a ceiling beam to escape a rampaging snake inside her home.

The family called for help from neighbours when they noticed the 5ft rat snake slithering their house in Roi Et, northern Thailand.

Footage shows the man searching through a pile of household items where the snake had taken cover.

He managed to coax the serpent out, causing it to slither across the floor, sending the family screaming and scrambling for safety.

Amid the chaos, the pensioner who had difficulty walking astonished her relatives by leaping up and grabbing onto a concrete beam overhead.

With her legs tucked up, she clung to it like a professional gymnast, drawing laughter from her grandchildren despite the tense situation.

Moments later, the rescuer successfully caught the snake and dragged it outside, where he gripped its head and placed it into a sack.

The elderly woman, visibly relieved, calmly climbed down from the beam, laughing at the surreal encounter on June 2.

In another clip, the snake wrangler opened the nylon bag and released the unharmed serpent back into the forest.

The Oriental rat snake is a non-venomous reptile that can grow up to 6.6 ft (2 m) in length.
