'CSI' and 'Hangover' Actor Busted for Sex Crime and Impersonating a Police Officer

June 7, 2011— -- The 32-year-old "CSI" actor who was arrested last week for impersonating a cop in order to force a woman to have sex with him is scheduled to appear in a Las Vegas court today.

Douglas Brian Irvin Jr., who played bit roles as a cop on "CSI" and as a VIP hotel guest in "The Hangover," faces five counts of sexual assault and impersonating a police officer, a spokeswoman for the Clark County Justice Court told ABCNews.com. He is being detained at the Clark County Detention Center following his arrest last Thursday in Las Vegas.

CBS, which airs "CSI," did not respond to repeated requests for comment.

According to the arrest report obtained by ABCNews.com, Irvin arranged for a masseuse, who goes by the name "Isabella," to meet him in a hotel room at Hooters casino May 15.

Isabella told police that she met "Mark," whom she later identified as Irvin, with the intention of giving him a sensual body rub for $180.

Mark told her that he was a rich plastic surgeon, and that "money was no object," the report stated.

Irvin began to touch Isabella sexually against her will. When she told him to stop, he offered her $10,000 for sex, according to the report.

Isabella told detectives she agreed -- with the condition that Irvin pay her up front and wear a condom.

Irvin then pulled out a laminated identification card that said "police," she said. The card had his photo and a name underneath.

Irvin told Isabella that he was a vice detective, and that "she was in lots of trouble," according to the report. He told her "she could either go to jail or have sex with him for free," the report stated.

Describing Irvin's demeanor as "very cop-like," Isabella said she believed he was a legitimate officer and agreed to have sex with him to avoid getting arrested.

Two days later, she went to police and filed a report that she had been sexually assaulted.

Detectives arrested Irvin on Thursday when he checked in with his parole officer, the Las Vegas Review Journal said.

After changing his story several times, the bit actor admitted to having sex with Isabella but told police it was consensual.

He denied impersonating a police officer, but, upon searching him, police found a laminated card with Metropolitan Police Department listed on it.

Irvin said he might have accidentally shown Isabella the card while taking out his driver's license.

When detectives checked Irvin's cellphone, they found several photos of him in police uniforms and one photo of a police ID card identifying him as a "special agent." Irvin told police the photos were from his work on "CSI."

According to the Internet Movie Database, Irvin, who goes by the name Brian Irvin, had uncredited roles in "CSI" and "The Hangover." He was also an intern on three episodes of "ER" and played an FBI agent in the 2008 video release "Stargate: The Ark of Truth." He made his big screen debut in 2009's "Race to Witch Mountain" with Dwayne "The Rock" Johnson.

Irvin's bio on IMDB states: "He's one of those actors we feel close to because of his chameleon character and charm he woos us with."
