Pretoria - A throng of journalists began entering the North Gauteng High Court at 8.23am on Monday ahead of Paralympian Oscar Pistorius's murder trial.
A court official pleaded with media waiting to enter court room GD not to block the door.
Police investigating officer Vineshkumar Moonoo arrived in court, and Captain Mike van Aardt emerged from inside the court room.
Pistorius, 27, is accused of murdering his girlfriend Reeva Steenkamp at his Pretoria home last year. He faces charges of premeditated murder and contravening the Firearms Control Act in a trial which is expected to last at least three weeks.
The proceedings in the wood-panelled courtroom will be broadcast live on television and radio, with the initial indictment listing 107 witnesses to testify for the State. The trial was due to start at 10am.
