Riah Phiyega recalled to Marikana Inquiry
The national police commissioner will have to answer more questions at the inquiry.
Phiyega testified last year, claiming police were forced to use live ammunition to defend themselves against protesters during an unprotected strike at Lonmin Platinum's Marikana mine.
The commission is investigating the deaths of 34 mineworkers who were shot dead during a police operation and 10 others who were killed in the days leading up to the shooting.
It's understood that retired Judge Ian Farlam will be asking most of the questions today when the national police commissioner returns.
An expert police witness has testified that the operation on Marikana two years ago was an executive decision imposed on officers.
Phiyega has already defended the police's conduct but will come under fire again today and has to try and justify why police officials resorted to live ammunition.
The commission is set to wrap up proceedings at the end of this month, before handing over recommendations to the Presidency.
