An investigation into the use of private investigators by Police has revealed that 16 officers gave information to the private investigation firm Thompson and Clark.
Another four officers were undertaking secondary employment with private security firms, Police said in a statement.
The Police review, which began in September following the start of a wider State Services Commission probe into the use of private investigators by government agencies, went back 15 years.
The review identified 16 people who had demonstrated behaviour which requires further
consideration under the Police Code of Conduct. All these instances related to the disclosure of information to Thompson and Clark Investigations Limited (TCIL).
All had been referred to the Professional Conduct group.
