A criminal case was lodged against the National Police Commissioner Khehla Sitole on 9 December coming from the Independent Police Investigative Directorate.
Police watchdog Ipid said that National Police Commissioner Khehla Sitole has a duty to cooperate with its investigations by providing information and availing himself for interviews when required.
Ipid said that Sitole had failed to do just that by not cooperating with its investigation into the murder of organised crime investigator, Charl Kinnear.
Ipid has registered the criminal case at the Pretoria Police Station and it has escalated his failure to Police Minister Bheki Cele.
Kinnear was shot dead in September 2020, outside his Bishop Lavis home in Cape Town.
A court has already found Sitole guilty of breaching his duties.
President Cyril Ramaphosa announced his intention to suspend Sitole back in October.
He remains in charge of the South African Police Service.
The Police Ministry confirmed it has received the information on the charges from IPID.
It says the letter will be referred to the president.
Meanwhile, IPID says the letter to the minister was confidential and condemned the leak.
