The leading forms of corruption in the police were abuse of power (35.7%) and bribery (30.6%).
Whistle-blowers alleged that the police network of patronage protected the corrupt and punished those striving to blow the whistle on graft, or members of the public seeking help after filing a case.
According to the report, corruption in schools stood at 30.6%.
“This is often at the hands of principals, school officials and school governing body members who deploy elaborate schemes to steal funds and divert resources that are intended to enhance learner education and environment.
“This constitutes a violation of human rights at the most fundamental level.”
