A 52-year-old man was arrested on Saturday after pouring a bottle of petrol on his wife and setting her alight.
Police said farmer Ten Lieth from Svay village in Preah Vihear province arrived home drunk at 7.30pm after drinking rice wine with friends.
He ordered his wife Neth Hon, 50, to prepare him a meal but she refused, complaining about his bad attitude, daily drinking habit, and not helping her with work.
Veng Song, deputy chief of Ronakse commune police, said: “He was angry at his wife for complaining about him and not preparing his meal.
“He beat her, grabbed her, and brought her down to the front of the house.
“He took a bottle containing a litre of petrol, poured it on her body and burned her,” he said.
“After burning the victim, he fled but he was arrested by police the same night.”
While his wife was still alight, neighbours intervened. She is being kept at the provincial referral hospital for treatment to injuries on her right hand and back.
A Sangkum Thmey district police officer said Mr Lieth was preliminarily accused by police of an “intentional act of violence”.
He is to be sent to the provincial court for questioning today.
