The Farlam Commission of Inquiry has heard that National police commissioner Riah Phiyega knew there was evidence to suggest that one of the crime scenes where 34 Marikana protesters were shot dead by police on the 16th of August had been tampered with.
Police spokesperson Ismael Semenya said the matter came to Phiyega's attention two weeks ago and that she immediately launched a probe to establish what had happened.
Semenya said it had become apparent that photographs taken on the night of August 16 showed more traditional weapons around the bodies of the slain miners than photographs taken earlier that day.
Last week Semenya said the integrity of the crime scene could have been compromised by the presence of paramedics who had asked that weapons be removed so they could do their work.
