(a) Refund.--If a contributing member of the police pension fund ceases to be a member of the police force before becoming entitled to a pension, the total amount of the contributions paid into the pension fund by the member shall be refunded to the member in full, without interest.
(b) Return of amount contributed.--If the fund has returned to the member the amount contributed and afterward the individual again becomes a member of the police force, the member shall not be entitled to the pension designated until 20 years after the member's reemployment, unless the member returns to the police pension fund the amount withdrawn. If a member returns to the pension fund the amount withdrawn, the period of 20 years shall be computed from the time the member first became a member of the police force, excluding the period of time during which the member was not employed by the police force.
(c) Payment to member's estate.--If a member of the police force dies not in the line of service before the member becomes entitled to a pension and the member is not survived by a spouse or family entitled to payments as provided in this subchapter, the total amount of contributions paid into the pension fund by the member shall be paid over to the member's estate.
