This is the terrifying moment a killer python was found lurking under a teenage boy’s bed.

The snake was found under the bed after it slithered through into the window of their bed - after killing the family’s kitten.

Thanapoom Lekyen, 42, said she had found the cat outside under the window ledge with a series of bite wounds when she entered her son’s bedroom in the morning last week then fled in terror after she spotted the animal’s shiny scales under the mattress.

Fortunately her son, Nong, 13, had been sleeping in his mother’s room the night before and avoided being savaged by the serpent, reports The Mirror.

She said, ‘I woke up in the morning and saw the dead cat outside with bite marks on it.

‘Then I knew there was a problem and I shivered and my stomach was feeling sick. I was scared.

‘I looked in my son’s bedroom and screamed when I saw something moving under the bed.

‘I think about what might have happened and cry. My son was very lucky because he did not sleep in the room that night.’

‘There must have been some guardian angel watching over him. He fell asleep with me and I decided to let him stay in that room instead of go to his normal room.

‘The snake came in through his window. If he was sleeping in the bed, he’s only small and it could have killed him.’

After making her terrifying discovery, Lekyen called the local animal rescue centre which dispatched Nattapon Boonmee with a pole and a lasso to catch the snake.

The footage shows Boonmee wrestling with the reptile which bite him with its razor-sharp fangs as he fought to subdue it.

He said: ‘The snake was average size but very, very aggressive. My hand was bleeding from where it bit me just a little bit.

‘A more powerful bite would be very, very dangerous.’

Rescuers were eventually able to pick the snake inside a canvas bag and released back into the wild unharmed near the family’s home in Chaochoengsao, Thailand.
