Be careful of going naked on Hawaiian beaches now as you will risk being captured along one of them.

Signs along the highway near Mokuleia Beach in Oahu, the third largest island in the US state of Hawaii, emphasize that nudity is an illegal activity that could lead to an arrest and fine, news Microsoft’s portal MSN reported.

One man was captured for open lewdness recently, it said.

Residents in the north-facing coastal area of Oahu are urging visitors to keep their swimsuits on because they have become increasingly upset by beach nudity.

“We like for our family to just relax, have fun," the portal quoted local William Kahapea as saying. "To see someone just turning over, bare-naked, is kind of disturbing."

Mokuleia, an isolated stretch on Oahu’s North Shore, is known as one of the most undeveloped shoreline locations with sandy beaches and blue pure water full of seashells to be collected.

It has also built a reputation as a gay-friendly nude spot where beachgoers can shed their clothes while sunbathing.

But local dwellers feel really vexed now that the nude crowds are getting more visible, blatant, and inappropriate.

The beach seems to be stolen away from locals who prefer enjoying their own community, Mike Dailey, a Mokuleia resident, complained.

"We hope something can be done to return this beach back to the community," Dailey said.
