Police 'lied about Marikana mining massacre' "We have obtained documents which give the impression that they are contemporaneous documents, but which appear in fact to have been constructed after the events to which they refer," the commission said. The commission said it will adjourn until next Wednesday to enable investigators to trawl through the "thousands of pages" which police officers had handed to the commission. The commission was appointed by Jacob Zuma, the South African president, to investigate the police killing of 34 striking miners on August 16 last year at a mine run by platinum giant Lonmin. In the run-up to the deaths, at least 10 other people - including two police officers - were killed during the highly charged strike.
