A man threatened his wife with a knife after she refused to have sex with him because of his body odour, reported China Press.
The 50-year-old had asked his wife, a 48-year-old bank manager, for sex after he returned to his home in Taming Jaya, Kajang, at about 3.30am on Friday.
However, she said he had body odour and refused him.
The angry man then started lashing out at their 20-year-old son before going into the kitchen and picking up a knife.
He then threatened his wife by holding the weapon to her neck.
The son managed to stop his father, and then helped his mother lodge a police report.
The man was arrested at home the following day.
