The trial of former North West Deputy Police Commissioner and three other senior officials will resume on Thursday after hitting a snag at the North West High Court sitting in Mogwase.

The four were charged with concealing the death of one of the 34 slain Marikana workers.

General William Mpembe and his co-accused have been implicated in the crime by two police officers who have turned state witnesses.

However, key documentation for cross-examination of the witness by the defence is outstanding.

Day three of the trial saw a drastically reduced number of people attending.

Accused Mpembe, Brigadier Gideon van Zyl, Colonel Dingaan Madoda and Captain Oupa Pule appeared calm in the dock.

On the witness stand, facing tough cross examination from both councils is Brigadier Samuel Seboloki who was overseeing the centre where arrested mine-workers in August 2012 were kept.

However, cross examination by the councils was marred by adjournments.

This is as some of key documentation, including statements made by investigators were not available. The court then rolled over the case to Thursday.

Meanwhile, last week Friday marked the 7th anniversary of the 2012 Marikana tragedy.
