Reality television's Vincent "Don Vito" Margera, uncle of "Viva La Bam" star Bam Margera, was held without bond Saturday on a charge of sexual assault on a child.

Margera, 50, was arrested Friday night after a skateboarding event at a Lakewood mall. He is accused of two incidents of sexual assault on a child, city spokeswoman Stacie Oulton said. She said the charges involved inappropriate touching.

The MTV show "Viva La Bam" focuses largely on Bam Margera playing practical jokes on his parents and uncle, whose dialogue is often unintelligible.

Vincent Margera came to Colorado to film promotional material for ManiaTV.com, which first reported his arrest. ManiaTV.com founder Drew Massey said Margera had finished his work before the arrest.

Bam Margera, a professional skateboarder, was not with his uncle on the trip.
