AUSTIN (KXAN) – Another public lewdness bust ended with four arrests in a North Austin park.

When officers conducted their sting operation in Walnut Creek Park last Friday, they arrested four men on charges of indecent exposure and public lewdness.

This is not a new problem, however.

Police said men — many of them married — use open areas of the park as a meeting place for sex. They said used condoms, discarded underwear and other evidence litter the wooded areas.

A check of our KXAN News archives shows we’ve been reporting similar stories since 2005, with police setting up regular stings every year or two.
