He is currently under investigation for the multi-million rand heist at OR Tambo International Airport in 2017.
Tshabalala‚ who TimesLIVE has been told began working again as a SAPS covert crime intelligence officer in 2017‚ was acquitted in the Sasolburg heist trial.
Naidoo declined to comment on how Tshabalala joined the police despite being convicted for the Mamelodi heist‚ his roles within the SAPS or who authorised his current re-employment into the covert crime intelligence unit.
A person with a criminal record can only be re-enrolled with the authorisation of the national police commissioner.
Naidoo said: "Given the nature of the environment Tshabalala was once part of‚ and that there is a court process currently under way in which there may be a need to provide certain information‚ we will not be responding to your query in detail."
Tshabalala appeared in court on Thursday after he was arrested on Tuesday by Independent Police Investigative Directorate [Ipid] officers as he checked in with his parole officer in Pretoria. His arrest is believed to have come after complaints from fellow officers after he returned to duty in 2017.
