LAS VEGAS (AP) -- Paris Hilton was arrested late Friday after a police motorcycle officer smelled marijuana smoke wafting from a black Cadillac Escalade driven by her boyfriend on the Las Vegas Strip, then found cocaine in her purse, authorities said.
A crowd quickly gathered when Hilton and Las Vegas nightclub mogul Cy Waits were stopped about 11:30 p.m. Friday in the vehicle near the Wynn Las Vegas resort on Las Vegas Boulevard, police said. The 29-year-old celebrity socialite asked to go into the hotel for privacy because of the number people gathering, said Officer Marcus Martin.
Police later found a substance in Hilton's purse that tests showed to be cocaine, Martin said. He said it was "a small amount" of the drug, a package of the size usually associated with personal use.
Hilton was arrested on suspicion of felony cocaine possession.
Waits, 34, was arrested on misdemeanor suspicion of driving under the influence of alcohol or drugs.
Both were booked into the Clark County jail, where Martin said Hilton was released without bail about 2:45 a.m. Saturday. Sgt. John Sheahan said Hilton received no special treatment during her brief time at the jail, and that release without bail was common in such cases.
Less than an hour later, Hilton's Twitter account was updated with a posting that said the actress was in bed watching the television show "Family Guy," and then that she was going to sleep. It was unclear if the tweets came from her, were posted by time-release or were sent by someone else.
If convicted of the low-grade felony, Hilton would get probation. Any violation of probation would be punishable by one to four years in Nevada state prison.
Clark County District Attorney David Roger declined comment Saturday about the case.
Hilton's attorney, David Chesnoff, told The Associated Press on Saturday morning that he was still gathering facts about the arrest.
"This matter will be dealt with in the courts not in the media and I encourage people not to rush to judgment until all of the facts have been dealt with in a court of law," Chesnoff said later in a statement. "There will be no interviews and no more comments at this time."
Waits' lawyer, Richard Schonfeld, said Waits posted $2,000 bail and was expected to be released Saturday.
Court appearance dates for Hilton and Waits were not immediately available.
Schonfeld said he was "troubled by the circumstances" leading to the arrest, but declined to specify his concerns.
"As the case proceeds, a lot of facts are going to come to light that will ultimately lead to exoneration," Schonfeld said.
A spokeswoman for Wynn Resorts in Las Vegas did not immediately respond to messages seeking comment.
Waits and his twin brother, Jesse, are managing partners of the Tryst Nightclub inside Wynn Las Vegas, Drai's after hours club at Bill's Gamblin' Hall & Saloon, and XS The Nightclub at Wynn's Encore resort. A spokeswoman for Harrah's resorts declined immediate comment.
Earlier this week, Hilton was in the news when a 31-year-old man allegedly tried to break into her Los Angeles home.
Authorities have said that someone carrying two big knives banged on Hilton's window Tuesday. She posted a photo of the arrest on Twitter and described it as "scary." Nathan Lee Parada faces a felony burglary charge.
Hilton was arrested this summer after the Brazil-Netherlands World Cup match in Port Elizabeth, South Africa, on suspicion of possession of marijuana. The case was then dropped at a midnight court hearing.
Hilton pleaded no contest in 2007 to alcohol-related reckless driving and was sentenced to 45 days in jail. After spending about 23 days in jail, Hilton told CNN host Larry King that the experience caused her to re-evaluate the role partying played in her life. She said she wanted "to help raise money for kids and for breast cancer and multiple sclerosis."
While most famous for her tabloid exploits and reality TV series "The Simple Life," Hilton has appeared in the films "Bottoms Up," "The Hottie & the Nottie" and "House of Wax."
