The rules of criminal procedure provide that anyone arrested, with or without warrant, be taken before a magistrate for the purpose of setting bail without "unnecessary delay."
What an unnecessary delay is, would depend entirely on the circumstances.
By rule of court, in order to detain a person arrested without a warrant, a determination must be made whether there is probable cause to continue to detain the arrestee within 48 hours after the arrest, otherwise, there is no hard and fast rule.
Generally, if a prisoner is held after arrest for an "unreasonable" period of time without being brought before a judge, a court would order release on a writ of habeas corpus.
Decisions on the issue of delay between arrest and arraignment deal primarily with admissibility of evidence obtained from an accused during an unreasonable delay.
Evidence, usually a confession, may be suppressed if the delay is unreasonable and is a contributing factor to the production of the evidence. Most county or district attorneys have a policy of issuing a "kickout letter" to the jail, if it comes to their attention that a person has been held without charges being filed within a certain amount of time, probably 36 hours, but perhaps up to 72 hours.
Even then, there might be exceptions, in their judgment, justifying a longer period. And if the situation does not come to their attention, they will do nothing.
