      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, special policeman appointed under section 29-18b, Department of Motor Vehicles inspector appointed under section 14-8 and certified pursuant 
to section 7-294d, or an authorized official of the Department of Correction or the Board 
of Pardons and Paroles 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, special 
policeman appointed under section 29-18b, Department of Motor Vehicles inspector 
appointed under section 14-8 and certified pursuant to section 7-294d, or authorized 
official of the Department of Correction or the Board of Pardons and Paroles is justified 
in using physical force upon another person when and to the extent that he or she reasonably believes such to be necessary to: (1) Effect an arrest or prevent the escape from 
custody of a person whom he or she reasonably believes to have committed an offense, 
unless he or she knows that the arrest or custody is unauthorized; or (2) defend himself 
or herself 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, special policeman appointed under section 29-18b, Department 
of Motor Vehicles inspector appointed under section 14-8 and certified pursuant to 
section 7-294d, or authorized official of the Department of Correction or the Board of 
Pardons and Paroles is justified in using deadly physical force upon another person for 
the purposes specified in subsection (b) of this section only when he or she reasonably 
believes such to be necessary to: (1) Defend himself or herself 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 or she 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 or she has given warning of his or her 
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, special policeman appointed under section 29-18b, Department of Motor Vehicles inspector appointed under section 14-8 and certified pursuant 
to section 7-294d, or authorized official of the Department of Correction or the Board 
of Pardons and Paroles to assist such peace officer, special policeman, motor vehicle 
inspector 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 or she reasonably 
believes such to be necessary to carry out such peace officer's, special policeman's, 
motor vehicle inspector's or official's direction.
      (e) A person who has been directed to assist a peace officer, special policeman 
appointed under section 29-18b, Department of Motor Vehicles inspector appointed 
under section 14-8 and certified pursuant to section 7-294d, or authorized official of the 
Department of Correction or the Board of Pardons and Paroles 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 or she reasonably believes 
such to be necessary to defend himself or herself or a third person from what he or she 
reasonably believes to be the use or imminent use of deadly physical force; or (2) he or 
she is directed or authorized by such peace officer, special policeman, motor vehicle 
inspector or official to use deadly physical force, unless he or she knows that the peace 
officer, special policeman, motor vehicle inspector or official himself or herself is not 
authorized to use deadly physical force under the circumstances.
      (f) A private person acting on his or her own account is justified in using reasonable 
physical force upon another person when and to the extent that he or she reasonably 
believes such to be necessary to effect an arrest or to prevent the escape from custody 
of an arrested person whom he or she reasonably believes to have committed an offense 
and who in fact has committed such offense; but he or she is not justified in using deadly 
physical force in such circumstances, except in defense of person as prescribed in section 
53a-19.

      Defendant's firing of warning shot at fleeing assailants constituted use of deadly force proscribed by statute. To permit
