      Sec. 53a-22. Use of physical force in making arrest or preventing escape. (a) For purposes of this section, a reasonable belief that a person has committed an offense means a reasonable belief in facts or circumstances which if true would in law constitute an offense. If the believed facts or circumstances would not in law constitute an offense, an erroneous though not unreasonable belief that the law is otherwise does not render justifiable the use of physical force to make an arrest or to prevent an escape from custody. A peace officer or an authorized official of the Department of Correction who is effecting an arrest pursuant to a warrant or preventing an escape from custody is justified in using the physical force prescribed in subsections (b) and (c) of this section unless such warrant is invalid and is known by such officer to be invalid.

      (b) Except as provided in subsection (a) of this section, a peace officer or authorized official of the Department of Correction is justified in using physical force upon another person when and to the extent that he reasonably believes such to be necessary to: (1) Effect an arrest or prevent the escape from custody of a person whom he reasonably believes to have committed an offense, unless he knows that the arrest or custody is unauthorized; or (2) defend himself or a third person from the use or imminent use of physical force while effecting or attempting to effect an arrest or while preventing or attempting to prevent an escape.

      (c) A peace officer or authorized official of the Department of Correction is justified in using deadly physical force upon another person for the purposes specified in subsection (b) of this section only when he reasonably believes such to be necessary to: (1) Defend himself or a third person from the use or imminent use of deadly physical force; or (2) effect an arrest or prevent the escape from custody of a person whom he reasonably believes has committed or attempted to commit a felony which involved the infliction or threatened infliction of serious physical injury and if, where feasible, he has given warning of his intent to use deadly physical force.

      (d) Except as provided in subsection (e) of this section, a person who has been directed by a peace officer or authorized official of the Department of Correction to assist such peace officer or official to effect an arrest or to prevent an escape from custody is justified in using reasonable physical force when and to the extent that he reasonably believes such to be necessary to carry out such peace officer's or official's direction.

      (e) A person who has been directed to assist a peace officer or authorized official of the Department of Correction under circumstances specified in subsection (d) of this section may use deadly physical force to effect an arrest or to prevent an escape from custody only when: (1) He reasonably believes such to be necessary to defend himself or a third person from what he reasonably believes to be the use or imminent use of deadly physical force; or (2) he is directed or authorized by such peace officer or official to use deadly physical force, unless he knows that the peace officer or official himself is not authorized to use deadly physical force under the circumstances.

      (f) A private person acting on his own account is justified in using reasonable physical force upon another person when and to the extent that he reasonably believes such to be necessary to effect an arrest or to prevent the escape from custody of an arrested person whom he reasonably believes to have committed an offense and who in fact has committed such offense; but he is not justified in using deadly physical force in such circumstances, except in defense of person as prescribed in section 53a-19.

(2) of Subsec. (c) to add provision that the felony involve the infliction or threatened infliction of serious physical injury and that the officer or official give a warning if feasible of his intent to use deadly physical force; P.A. 86-403 made technical change in Subsec. (b); P.A. 92-260 made technical changes by replacing "believes it necessary", "believes that such is necessary" and "believes it is necessary" with "believes such to be necessary"; May Sp. Sess.

      Defendant's firing of warning shot at fleeing assailants constituted use of deadly force proscribed by statute. To permit persons to fire warning shots would frustrate purpose of statute to limit use of guns to emergency situations to protect persons from death or great bodily harm. 35 CS 570, 575, 576.
