Sec. 14. REFUNDS ON LEAVING SERVICE. If any such member shall leave such police department either voluntarily or involuntarily before he is entitled to a pension, he shall have refunded to him the deductions from his salary, which have been paid into said pension fund. Said payments may be made to him, either in a lump sum or on a monthly basis, as may be determined by the pension board.

Provided, however, that this Section shall be subject to Section 10 and upon a re-entry into the department all such refunds shall be paid back into the pension fund or prior service of such member shall not be counted toward his retirement pension.
