Indiana Code Title 36. Local Government § 36-8-6-9

Sec. 9. (a) Benefits paid under this section are subject to section 1.5 of this chapter.

(b) The 1925 fund shall be used to provide a member of the police department who retires from active duty after twenty (20) or more years of active duty an annual pension equal to fifty percent (50%) of the salary of a first class patrolman in the police department, plus:

of the retired member over twenty (20) years.  However, the pension may not exceed in any year an amount greater than seventy-four percent (74%) of the salary of a first class patrolman.  The pensions shall be computed on an annual basis but shall be paid in not less than twelve (12) equal monthly installments.  If the salary of a first class patrolman is increased or decreased, the pension payable shall be proportionately increased or decreased.

(c) If a member voluntarily retires after twenty (20) or more years of service, the member is entitled to retirement and the pension, without reference to the member's physical condition at the time of application.  However, the member then relinquishes all rights to other benefits or pensions for temporary disability.  After retirement the member is not required to render further services on the police department, is no longer subject to the rules of the department, and may not be deprived of other benefits under this chapter that may accrue to the member or the member's dependents.

(d) To be retired based upon length of service, only the time served by the member on the regularly constituted police department may be computed.  Time served by a member as a special police officer, a merchant police officer, or a private police officer may not be considered in computing length of service.
