'Bounty Hunter' sidekick is accused of lewdness

A sidekick of TV bounty hunter Duane "Dog" Chapman turned himself in to authorities Friday after a shopping center security guard in Honolulu reported seeing him naked in his pickup truck, performing a lewd act, police said.

But Tim Chapman's lawyer insists his client spilled juice on himself and was just changing clothes Thursday night.

The guard told Chapman to put on his clothes and get out of the truck, police said. After dressing, Chapman started his truck and drove over a sidewalk, nearly hitting the guard, then drove off, police said.

The guard told police that he recognized Chapman from Duane Chapman's show "Dog the Bounty Hunter" and that he was performing an unspecified lewd act. Duane Chapman and Tim Chapman are not related.

Police said they were investigating whether to charge Chapman, 42.
