Lindsay Lohan.. DUI.. Cocaine.. You know.. Saturday

Lindsay Lohan was arrested and cited for driving under the influence in Los Angeles in the wee hours of Saturday morning, say police, who also found a substance tentatively identified as "a usable amount of cocaine" in connection with the accident. The 20-year-old actress was slightly injured when her 2005 Mercedes SL-65 convertible struck a curb and shrub on Sunset Boulevard. The car suffered "major damage," according to police. Lohan and two other people were in the vehicle when it crashed around 5:30 a.m., Lt. Mitch McCann, media relations officer for Beverly Hills police department, said during a press conference Saturday. The star was hospitalized for minor upper chest injuries. The passengers were not hurt. Police learned of the accident when they received a 911 call at 5:30 a.m. There was also a witness on the scene, but police do not know if the same person called 911. By the time authorities responded, three minutes after the call, Lohan, her companions and the car were gone from the scene. Lohan was later located by police at the Century City Hospital. Her car was found at a nearby condo complex and towed at 6:30 a.m. Police won't say how they know that the actress was driving, but say they're "confident" that she was. At the press conference McCann said: "A usable amount of an illegal narcotic tentatively identified as cocaine was recovered and booked." Police would not specify where the drugs were found. McCann also declined to comment on Lohan's blood-alcohol level. "She was charged with a misdemeanor," said McCann. "There is a potential for additional charges." Her tentative arraignment date is Aug. 24.
