Cape Town - The Independent Police Investigative Directorate (Ipid) has said the case involving the mistaken shooting deaths of Nando's and McDonald's employees in Cape Town in March cannot be delayed any longer.

Ipid spokesperson Robbie Raburabu told News24 on Tuesday that the police officers involved have yet to give statements. He said they had asked early in the process to do this through legal representatives.

"In my view, the police should not have delayed the case. We're having problems with a certain unit of the police.
