The Mayor shall have general supervision over each department and the officers provided for in Title VII of the Revised Code. When the Mayor has reason to believe that the head of a department or an officer has been guilty, in the performance of his official duty, of bribery, misfeasance, malfeasance, nonfeasance, misconduct in office, gross neglect of duty, gross immorality, or habitual drunkenness, he shall immediately file with the Council, except when the removal of the head of the department or officer is otherwise provided for, written charges against the person, setting forth in detail a statement of alleged guilt, and, at the same time, or as soon thereafter as possible, serve a true copy of the charges upon the person against whom they are made. Service may be made on the person or by leaving a copy of the charges at the office of the person. Return thereof shall be made to the Council, as is provided for the return of the service of summons in a civil action.
