Skateboarder Ryan Sheckler Victim of Vegas Jewelry Heist

Ryan Sheckler -- a world-class skateboarder who has also ventured into reality TV -- had nearly $100k worth of jewelry stolen from his Las Vegas hotel room while he was snoozing, and the woman he planned on spending the night with has been arrested.

According to the police report, obtained by TMZ, on February 27, Ryan was staying at the Palms Hotel and at 3:45 AM he took Stacy Salazar back to his room -- a woman he says he's known for 4 years.

Ryan claims he fell asleep but was awakened by the sound of his door closing. He then noticed Stacy was no longer in his room. A few hours later he noticed his jewelry was missing -- a Rolex watch valued at $12,500, a gold/diamond bracelet worth $14,975, a diamond and white gold ring ($63,275) and a diamond necklace of unknown value.

Ryan called the cops, who took a report.

The security camera shows Ryan and Stacy taking the elevator up to the room, and cops observed the Rolex on Ryan's wrist.

As for Stacy, the security camera shows her leaving Ryan's room at 5:05 AM. According to the police report, "As she is walking she is fumbling with her purse that she carries over her shoulder." She got to the elevator, wedged the door open at the last minute, got out, went to Ryan's room where they spoke at the door for one minute, and then she left.
