A 'Facebook rapist' has been discovered dead in a South African prison.

According to local media sources, South African inmate Thabo Bester, commonly known as the Facebook rapist for utilizing the social networking site to seduce his victims, was found dead in his jail cell.

A spokeswoman for the Department of Correctional Services (DCS) confirmed the death at the Mangaung Correctional Centre in Bloemfontein.

According to Singabakho Nxumalo, an investigation into the cause of death is underway.

According to national broadcaster SABC, Mr. Nxumalo stated, "He was discovered at about 03:35 this [Tuesday] morning when his cell was burnt, and he was lying on the floor."

Bester was doing time for the murder of a model in 2012.

He had previously been found guilty of rapping and robbing two aspiring models whom he had enticed via Facebook.
