Pretoria — Public hearings of the Farlam Commission of Inquiry were brought to a standstill on Monday afternoon by protesters.
The group banged on tables and clapped hands shouting "Ramaphosa must resign" and "blood on his hands."
Bodyguards rushed into the auditorium and many police officers stood at the entrance.
After a short while Dali Mpofu, for the arrested miners, managed to calm the protesters.
Chairman of the inquiry, retired judge Ian Farlam, said it was vital for Ramaphosa to be allowed to give his evidence.
