(a) Any member who terminates covered employment and is not eligible to receive disability or retirement income benefits under this article is, by written request filed with the board, entitled to receive from the fund the member's accumulated contributions after offset of any outstanding loan balance, plus accrued interest, pursuant to section twenty-three of this article. Except as provided in subsection (b) of this section, upon withdrawal the member shall forfeit his or her accrued benefit and cease to be a member.

(b) Any member of this plan who ceases employment in covered employment and active participation in this plan, and who thereafter becomes reemployed in covered employment may not receive any credited service for any prior withdrawn or offset accumulated contributions from either this plan or the Public Employees Retirement System relating to the prior covered employment unless following his or her return to covered employment and active participation in this plan, the member redeposits in this plan the amount of the withdrawn accumulated contributions submitted on salary earned while a deputy sheriff, together with interest on the accumulated contributions at the rate determined by the board from the date of withdrawal to the date of redeposit. Upon repayment he or she shall receive the same credit on account of his or her former service in covered employment as if no refund had been made. The repayment authorized by this subsection shall be made in a lump sum within sixty months of the deputy sheriff's reemployment in covered employment or if later, within sixty months of the effective date of this article.

(c) A member of this plan who has elected to transfer from the Public Employees Retirement System into this plan pursuant to subsection (b) of section five of this article may not, after having transferred into and become an active member of this plan, reinstate to his or her credit in this plan any service credit relating to periods of nondeputy sheriff service which were withdrawn from the Public Employees Retirement System plan prior to his or her elective transfer into this plan.

(d) Every member who completes sixty months of covered employment is eligible, upon cessation of covered employment, to either withdraw his or her accumulated contributions in accordance with subsection (a) of this section, or to choose not to withdraw his or her accumulated contribution and to receive retirement income payments upon attaining normal retirement age.

(e) Notwithstanding any other provision of this article, forfeitures under the plan shall not be applied to increase the benefits any member would otherwise receive under the plan.
