Twenty-one-year-old actress and singer Lindsay Lohan was arrested by Santa Monica police early Tuesday, July 24th, and booked for driving under the influence of alcohol (DUI), possession of cocaine and driving with a suspended or revoked license, police said.

Police received a call at about 1:35 a.m. from a woman who is the mother of Lohan’s personal assistant and reported that she was being chased by a vehicle in the area of Main Street and Pico Boulevard in Santa Monica, Lt. Alex Padilla said.

The personal assistant’s mother did not know who was chasing her and was trying to get to the Santa Monica Police Department but stopped near the Santa Monica Civic Auditorium parking lot, where she got into an argument with the driver of the other vehicle, Padilla said.

When officers arrived at the Civic Auditorium parking lot in the 1800 block of Main Street, they spoke to the drivers of the two vehicles, one of whom was Lohan, Padilla said.

Police were unsure why Lohan was reportedly chasing the other vehicle, he said.

Lohan had been driving a 2004 white GMC Yukon and the other driver, the assistant’s mother, was driving a 2007 black Cadillac Escalade. Lohan’s personal assistant had reportedly quit her job before the incident occurred, Padilla said.

While conducting a preliminary investigation at the scene, officers smelled alcohol on Lohan’s breath, Padilla said.

The actress failed a field sobriety test and was given the opportunity to take a preliminary alcohol screening test at the scene but she refused, Padilla said.

She was then arrested and taken to the Santa Monica Jail, where an alcohol breath test was administered to her. The tests revealed that Lohan had a blood alcohol level 0.12 and 0.13 percent, above the California legal limit of .08 percent, Padilla said.

When police were searching Lohan during the booking process, they also allegedly found a small amount of cocaine in her pocket, Padilla said.

The actress was “cooperative” with police during the investigation, Padilla said.

She was booked for driving under the influence of alcohol, possession of a controlled substance and driving with a suspended/revoked license.

The actress was released at 6:20 a.m. after posting $25,000 bond, Padilla said.

The arrest came after Lohan, who also faces a driving under the influence charge connected to a crash in Beverly Hills, recently spent more than a month in an alcohol rehabilitation facility.

The actress, who got her big screen debut with The Parent Trap in 1998, was scheduled to appear on The Tonight Show with Jay Leno the day of the arrest in Santa Monica. Her new movie, I Know Who Killed Me, is scheduled to open in theaters Friday, July 27th.
