92-year-old woman locked in a pigpen for years by her son and daughter-in-law

A 92-year-old woman was recently found living inside a grimy pigpen in Guangxi, China.

According to the Shanghaiist, her son and daughter-in-law kept her locked up for several years.

In a disturbing video that has gone viral on Chinese social media, the malnourished elderly woman can be seen in her prison, containing only a wooden board covered by an old blanket for her to sleep on.

The woman has since been rescued from the pigpen and transported to a hospital for treatment.
