Any person who shall knowingly make any false statement or shall falsify or permit to be falsified, any record or records of this retirement system in any attempt to defraud such system as a result of such act shall be guilty of a felony. Should any charge or error in the records result in any member or beneficiary receiving from the retirement system more or less than he would have been entitled to receive had the records been correct, the Board of Trustees shall correct such error, and so far as practicable, shall adjust the payment in such a manner that the actuarial equivalent of the benefit to which such member or beneficiary was correctly entitled shall be paid, and to take from the Interest Fund sufficient to reimburse the Fund where an overpayment had already been made, and any such overpayment recovered from the member shall be placed in the Interest Fund.
