As used in section 29-06-05, the term “fresh pursuit” shall include fresh pursuit as defined by the common law, and also the pursuit of a person who has committed or who is reasonably suspected of having committed a felony, misdemeanor, or traffic violation. It also shall include the pursuit of a person suspected of having committed a supposed felony, misdemeanor, or traffic violation, though no felony, misdemeanor, or traffic violation has been actually committed, if there is reasonable ground for believing that a felony, misdemeanor, or traffic violation has been committed. Fresh pursuit, as the term is used in this chapter, shall not necessarily imply instant pursuit, but pursuit without unreasonable delay.
