Any member of the county board of any county to which this Division applies, or any other person holding any other office, trust or employment under such county, who wilfully violates this Division shall be guilty of a business offense, and shall be fined not to exceed $10,000, and shall forfeit his right to his office, trust or employment and shall be removed therefrom. Any such member or other person is liable for any sum that is unlawfully diverted from the county working cash fund, or otherwise used, to be recovered by the county or by any taxpayer in the name and for the benefit of the county, in an appropriate action. Such a taxpayer must, however, file a bond for all costs, and be liable for all costs taxed against the county in suit, and judgment shall be rendered accordingly. The remedies provided by this Section are in addition to and not exclusive of any other remedy.
