The police department of any township or township police district may provide police protection to any county, municipal corporation, or township of this state, to a park district created pursuant to section 511.18 or 1545.01 of the Revised Code, or to a governmental entity of an adjoining state without a contract to provide police protection, upon the approval, by resolution, of the board of township trustees of the township in which the department is located and upon authorization by an officer or employee of the police department providing the police protection who is designated by title of office or position, pursuant to the resolution of the board of township trustees, to give such authorization.
Chapter 2744. of the Revised Code, insofar as it applies to the operation of police departments, shall apply to any township police department or township police district and to its members when such members are rendering police services pursuant to this section outside the township or township police district by which they are employed.
Police department members acting, as provided in this section, outside the township or township police district by which they are employed shall be entitled to participate in any pension or indemnity fund established by their employer to the same extent as while acting within the township or township police district by which they are employed. Those members shall be entitled to all the rights and benefits of Chapter 4123. of the Revised Code to the same extent as while performing services within the township or township police district by which they are employed.
