A Japanese housewife beat her 70-year-old husband to death with a coffee mug after discovering he had been cheating, local media reported.

According to "Asahi Shimbun" and other Japanese newspapers, the 61-year-old woman allegedly attacked her husband after she found out about his extramarital affair, hitting him repeatedly on the face and head with a cup, AFP reported.
