(1) A person who is found committing an indictable offence may be arrested by any other person without warrant, if the person making the arrest has reasonable grounds to believe that the offender may escape punishment, or may complete the commission of the offence, if he or she is not so arrested.
(2) Any person may, without warrant, arrest the person if such an offence has actually been committed, or if he or she is being pursued by a mob for committing such an offence.
