The Independent Police Investigative Directorate (Ipid) has arrested former national police commissioner Khomotso Phahlane and the police's supply management head Ravichandran Pillay on fraud and corruption allegations.
Ipid spokesperson Moses Dlamini said they were arrested on Friday morning and were due to appear in the Johannesburg Commercial Crimes Court on Friday.
"The arrests relate to procurement irregularities relating to emergency (blue) lights amounting to more than R86m," Dlamini said.
"Ipid conducted an investigation and gathered evidence of criminality."
Former Gauteng police commissioner Deliwe de Lange and four other people were arrested last year for tender fraud relating to the same matter. De Lange‚ Vimpie Phineas Manthata‚ Ramahlaphi Johannes Mokwena‚ James Ramanjalum and Nombhuruza Napo face charges of fraud‚ forgery and uttering.
They appeared in the Johannesburg Commercial Crimes Court in November last year and were granted bail.
