Ohio Revised Code Title XXIX. Crimes Procedure § 2935.16

When it comes to the attention of any judge or magistrate that a prisoner is being held in any jail or place of custody in his jurisdiction without commitment from a court or magistrate, he shall forthwith, by summary process, require the officer or person in charge of such jail or place of custody to disclose to such court or magistrate, in writing, whether or not he holds the person described or identified in the process and the court under whose process the prisoner is being held. If it appears from the disclosure that the prisoner is held solely under warrant of arrest from any court or magistrate, the judge or magistrate shall order the custodian to produce the prisoner forthwith before the court or magistrate issuing the warrant and if such be impossible for any reason, to produce him before the inquiring judge or magistrate. If it appears from the disclosure that the prisoner is held without process, such judge or magistrate shall require the custodian to produce the prisoner forthwith before him, there to be charged as provided in section 2935.06 of the Revised Code.

Whoever, being the person in temporary or permanent charge of any jail or place of confinement, violates this section shall be fined not less than one hundred nor more than five hundred dollars or imprisoned not more than ninety days, or both.
