A wife slashed her husband's penis off in Uganda after he refused to have sex with her as punishment for her continuous heavy drinking.

Beatrice Acen, 35, returned home plastered at 10pm on June 30 and proceeded to demand sex from her husband, Moses Okot, a 46-year-old peasant farmer.

Mr Okot said that he had returned home from hunting during the day, eaten and gone to sleep when his wife attacked him.
