( CNN ) -- Prosecutors in Clark County , Nevada , filed a felony charge against Paris Hilton on Monday stemming from her arrest over the weekend on suspicion of cocaine possession . Hilton was charged with possession of a controlled substance . She is set to be arraigned October 27 in Clark County District Court , according to courthouse spokeswoman Jillian Prieto . The hotel heiress , 29 , was arrested late Friday . Police pulled alongside a Cadillac Escalade in which Hilton was a passenger about 11:30 p.m. and smelled `` a strong odor of marijuana coming from the vehicle , '' according to the arrest report . When the officer looked over , `` the female passenger started to put the window of the vehicle up , '' the report said . Police told the driver of the Cadillac to pull over , which he did , in front of the Wynn Hotel . The driver , whom police identified as Cy Waits , 34 , was arrested for driving under the influence after he failed field sobriety tests , the report said . Waits is a Las Vegas nightclub mogul and Hilton 's rumored boyfriend . Authorities immediately recognized Hilton as the passenger , the arrest report said , but police did not want to release the vehicle to her following Waits ' arrest because of the continuing investigation and also because of the strong odor of marijuana emanating from the SUV . A large crowd began to gather at the side of the vehicle as people realized Hilton was inside , the report said . The police lieutenant who wrote the report , identified as D. Flynn , said he approached the vehicle and told Hilton she needed to get out , as police were going to search it for drugs . `` Hilton told me that she was extremely embarrassed , due to all the people taking pictures of her , and she did not want to be seen by them , '' the report said . She said she wanted to stay and see what was going to happen to Waits , but also needed to use the bathroom . She asked Flynn if he would escort her inside the Wynn Hotel to protect her from the crowd `` and also asked to go somewhere private and out of the public 's eye until the investigation was over . '' Flynn wrote that he took Hilton inside , and hotel staffers directed them to the security holding room , which was private and had a nearby restroom . The officer had Hilton place her purse on the table while the two awaited a female officer to accompany her to the restroom . `` While we were waiting for the female officer to arrive , Hilton said she needed to put some lip balm on , and I handed her the purse from the table , '' the report said . As she opened it , a bundle of what looked like cocaine in a plastic bag fell from the purse , and the lieutenant caught it . The officer put the bundle back insde the purse , waiting for other officers to witness it , he wrote . When other officers arrived , Flynn wrote that he opened the purse , removed the suspected bundle and read Hilton her Miranda rights . `` She told me the purse was not hers , and that she had borrowed it from a friend , '' the report said . However , Hilton did admit that a broken tablet of Albuterol , also found inside the purse , was hers and was prescribed to her , according to the report . Albuterol is commonly prescribed for diseases such as asthma . Hilton said several cosmetics inside the purse were not hers , but that $ 1,300 cash and credit cards in the purse were hers , the report said . She also said a package of Zig Zag papers , `` which are commonly used to roll and smoke marijuana , '' according to the report , were hers . `` I asked Hilton whose cocaine it was , and she said she had not seen it but now thought it was gum , '' according to the arrest report . Authorities placed her under arrest and transported her to the Clark County Detention Center , the report said . The substance was tested and confirmed to be 0.8 grams of cocaine . Hilton was released from jail Saturday morning after authorities determined she was not a flight risk , Lt. Wayne Holman told CNN . `` 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 , '' Hilton 's attorney , David Chesnoff , said in a statement Saturday . Last month , Hilton was briefly detained in South Africa for allegedly smoking marijuana at the World Cup . Her publicist called the July 2 incident `` a complete misunderstanding , '' and the case was dropped . In Session 's Carol Gantt contributed to this report .
Cocaine fell out of Hilton 's purse as she was shopping for lip rings , police said . She said the purse was n't hers , but some things in it were . Hilton is scheduled to appear in court October 4th .
