Each professional bondsman licensed under the provisions of this chapter may apply for a renewal of his license upon renewal application forms provided by the Commissioner of Emergency Services and Public Protection and requiring the disclosure of such information as said commissioner requires in determining whether or not such professional bondsman’s financial responsibility remains unimpaired or whether for any other reason such bondsman’s fitness to continue in such business has been otherwise altered since the issuance of any prior license. Said commissioner may suspend for a definite term or revoke any license issued under the provisions of this chapter if it appears to said commissioner that (1) such licensee has been convicted of a felony in this state or elsewhere, (2) such licensee is engaged in any unlawful activity affecting his fitness to continue in the business of professional bondsman, (3) the financial responsibility of such licensee has been substantially impaired, or (4) such licensee is subject to a restraining or protective order issued by a court in a case involving the use, attempted use or threatened use of physical force against another person.
