Thabo Bester has been free for a year following he was believed to have died in a fire he started in his prison cell, according to the BBC.
A search was launched last month following a new investigation showed the charred body was not his.
Bester was arrested on Friday along with his girlfriend and a suspect and will be extradited to South Africa. Police said the group intended to flee to Kenya.
Bester is known as the “Facebook Rapist” because he used the social network to lure his victims.
He was convicted in 2012 of the rape and murder of his girlfriend, model Nomfundo Tyhulu. A year earlier, he had been found guilty of raping and robbing two other women.
