Conn. Gen. Stat. § 53-392d: Enforcement by the Attorney General.

Whenever the Attorney General, or his deputy, has reason to believe that any person has violated any of the provisions of this chapter, he may bring an action in the superior court for the judicial district of Hartford to enjoin the continuance of such violation; and, if it appears to the satisfaction of the court that the defendant has, in fact, violated this chapter, an injunction may be issued enjoining and restraining any further violation, without requiring proof that any person has, in fact, been injured or damaged thereby. In connection with any such proposed application, the Attorney General may conduct an investigation, subpoena witnesses and documents deemed by him necessary to the conduct of such investigation and, in the event of noncompliance with any such subpoena, may apply to the superior court for the judicial district of Hartford, which may issue an order requiring such compliance.
