Flights, holidays, luxury vehicles, paying off journalists' cars and upgraded security in private homes are just some of the things the Crime Intelligence “slush fund” allegedly went towards.

The state capture inquiry heard testimony over the past two weeks about the fund from former Crime Intelligence officer Col Dhanajaya Naidoo and Hawks investigator Kobus Roelofse.

Naidoo's testimony is being held in camera from a secret location, as he is in witness protection.

The commission heard that journalists, ministers and government officials had allegedly benefited from the account.

Some have denied the allegations and none have testified before the commission. Evidence is ongoing.
