Mduduzi Mfundisi Nzuza and Sam Baloyi face charges of attempted murder, reckless endangerment, failure to take reasonable precautions to avoid danger, and negligent use of a firearm. Both are out on bail.
The trial was postponed on Monday when their lawyer, Tuelo Thomas, told the court that senior police officials asked to meet him about the case.
Chana was not present during court proceedings.
The officers allegedly shot at the award-winning musician’s car when he failed to stop at a roadblock they had set up at a petrol station on the N1 in Midrand on October 28 last year.
Chana, whose real name is Khulane Morule, was wounded in the hand and back.
At the time, police had been searching for a group of men who kidnapped a Bedfordview, Johannesburg, businessman. The officers allegedly mistook Chana’s luxury sedan for that of the kidnappers.
The ransom money was to have been left at the petrol station. A police officer has since been arrested and charged with the kidnapping.
