Sec. 24-8. Credit for good conduct; credit on fine and costs.
Prisoners shall be allowed a credit upon their term of imprisonment
at the rate of ten days per month for good conduct
when such term is on account of sentence imposed.
Where a prisoner is held in confinement for failure to pay
a fine and costs, he shall be allowed a credit on such fine and
costs of seventy-five cents per day, but nothing herein contained
shall prevent the city from collecting such fine and
costs or any part thereof by civil proceedings; provided, that
in the event of the wilful failure of any prisoner to work, the
credit allowed shall be twenty-five cents per day.
No credit shall be allowed on account of fine or costs until
after the service of any jail sentence imposed shall have been
completed. (Code 1959, § 24-8.)
