PHUKET: Jealousy and his stepsonís obsession with the internet drove an Australian real estate agent to burn down his house around him with his family inside, the manís wife told Krabi Town Police.

Naruthai Port, recovering in Krabi Hospital from serious burns across 60 per cent of her body, told police that Australian Richard Port locked all the doors to prevent anyone from escaping and then started the fire.

Ms Naruthai, 38, was rescued from the flames.
