Ohio Rev. Code § 505.491
Except as provided in division (D) of section 505.49 or in division (C) of section 509.01 of the Revised Code for a board of township trustees, and except as provided in division (D) of section 505.49 of the Revised Code for a joint police district board, if the board has reason to believe that a chief of police, patrol officer, or other township or joint police district employee appointed under division (B) of section 505.49 of the Revised Code or a police constable appointed under division (B) of section 509.01 of the Revised Code has been guilty, in the performance of the official duty of that chief of police, patrol officer, other township or joint police district employee, or police constable, of bribery, misfeasance, malfeasance, nonfeasance, misconduct in office, neglect of duty, gross immorality, habitual drunkenness, incompetence, or failure to obey orders given that person by the proper authority, the board immediately shall file written charges against that person. The written charges shall set forth in detail a statement of the alleged guilt and, at the same time, or as soon thereafter as possible, serve a true copy of those charges upon the person against whom they are made. The service may be made on the person or by leaving a copy of the charges at the office or residence of that person. Return of the service shall be made to the board in the same manner that is provided for the return of the service of summons in a civil action.
