Five people, who include a senior official from the Bloemfontein branch of the Department of Labour, and four civilians have been arrested in connection with fraudulent Unemployment Insurance Fund UIF claims.
The countrywide crackdown was launched five months ago.
One of the arrests so far was made in Gauteng while the others are from the Free State.
Police spokesperson Motantsi Makhele says arrests are ongoing.
Makhele says some of the suspects will be arrested in Bethlehem and parts of Gauteng.
