"Our teams' investigations are at a very advanced and critical stage. We cannot at this stage rule out the possibility of more arrests in this matter.”

While the G4S employee makes his first appearance on Thursday, the rest of the accused are expected back in court on 3 May, exactly a year since Bester staged his elaborate escape.
