After due investigation, the commissioner may cancel the liability of the fund for the acts of any public employee or public official. The cancellation takes effect thirty days after written notice. If a public official's or public employee's bond is canceled, the public official or public employee may secure at personal expense a bond executed by a duly authorized surety company in an amount determined by the commissioner. Evidence of a surety bond purchased under this section must be filed with the commissioner.
