Paris Hilton was arrested early Thursday for investigation of driving under the influence, police said.
Hilton was arrested shortly before 12:30 a.m. after being pulled over in Hollywood, said police Officer I. Isabella, who declined to give his first name.
Police stopped Hilton because she was "driving erraticly," he said.
"The officers observed that Hilton exhibited the symptoms of intoxication. A field sobriety test was conducted at scene, and the officers determined she was driving under the influence," Isabella said, reading a police statement.
Hilton was booked on suspicion of misdemeanor DUI and released, he said.
Her spokesman, Elliot Mintz, confirmed the arrest and said police detected the minimum blood-alcohol level to warrant an arrest. The legal limit in California is 0.08 percent
