Upon arrest, or upon appearance without arrest in response to citation or summons, or at any other time before trial, before or after arraignment, the defendant shall be eligible to be released upon giving bail for his appearance in an amount and upon conditions fixed by the judge, who shall prescribe appropriate rules of court for the receipt of bail and for the release on one's own recognizance. In case of arrests made at night or under other conditions of emergency or when the judge is not available, the rules can authorize the chief of police, or his designated representative, to accept a temporary cash bond, not more than the maximum monetary penalty provided by ordinance for such offense charged. The chief of police or his designated representative is authorized, subject to such conditions as shall be prescribed by the judge, to release a resident of Vinita on his own recognizance. (1986 Code § 12-24)
