An exhausted woman was freed from the coils of a large snake that had been wrapped around her body for almost two hours, at her house in Samut Prakan on Tuesday night.

Her calls for help were heard by a passing neighbour, who called for assistance about 10pm.

Rescuers had to break into the woman's locked house. They found 64-year-old Arrom Arunroj with a 4-metre-long python, weighing at least 20 kilogrammes, wrapped around her body. The woman was alive but exhausted. 

It took rescuers about 30 minutes to free her from the python's clutches. She was given first aid and then rushed to a nearby hospital. Rescuers said she had several bite wounds. Pythons are not venomous but their bite can cause infection.

Ms Arrom said she was washing the dishes at the back of the house, which is next to a forest.

While washing the plates, she felt a sharp pain on her right thigh, looked down and saw a huge snake attacking her. She grabbed its head and tried to pull it off her, but could not fight its strength. She rolled to the ground, with the snake wrapping itself around her body.

She had been trying to free herself and finally just fighting for breath and calling for help for about two hours before a passing neighbour heard her and phoned for help.

Ms Arrom is now recovering in hospital.
