A "China doll" learnt a painful lesson for cohabiting with a 72-year-old Malaysian man.

China Press reported on its front-page yesterday that the man's wife and about 10 members of his family stormed into the couple's love nest at a shop house in Klang on Saturday evening and caned the woman.

The wife decided to take the drastic step after the man failed to return home for three weeks.

After being continuously beaten for five minutes, the woman from China gave her word to the family members that she would stop her affair with the old man, according to the daily.

The family then brought the woman to the police station to lodge a report.

The woman's hands, legs and back were full of cane marks, said the daily.

When contacted, Klang OCPD Asst Comm Mohd Rodwan Yusof said police were investigating whether the woman was involved in prostitution.

"We will also determine whether she had overstayed her tourist visa," he said.
