OKLAHOMA CITY (AP) - A federal judge has denied a request from Occupy OKC for a preliminary injunction that would have allowed the protest group to continue camping overnight in a downtown Oklahoma City.

U.S. District Judge Timothy DeGiusti issued the ruling late Monday that allows the city to enforce an overnight curfew in the park from 11 p.m. to 5 a.m. A police spokesman said there was no plan to immediately enforce the curfew.

Protesters with Occupy OKC have maintained a continuous presence at the park since Oct. 11 as part of a demonstration over the disparity in wages between the working class and the wealthy, among other things.

The city cited deteriorating conditions and problems at the park as a reason for ending overnight camping.
