Lindsay Lohan was arrested early July 24 on suspicion of driving under the influence in Santa Monica, CA. The arrest comes one week after the 21-year-old actress checked out of an alcohol treatment center.

Santa Monica Police Sgt. Robert Hernandez says Lohan was driving a vehicle, and pulled over just after 2:00 a.m. She was reportedly chasing another car when she was pulled over.

Officers arrested her for drunken driving and driving with a suspended license.During booking, cocaine was found in her pants pocket.

Lohan reportedly refused to take a Breathalyzer test at the scene but failed a sobriety test. After taking a Breathalyzer test at the Santa Monica police station, she registered a .12 blood alcohol level. The legal limit in California is 0.08.

Lohan was released on $25,000 bail. Police say she will be arraigned on August 23.

The actress recently spent a month at Malibu's Promises treatment center, and is already facing a drunken driving charge in Beverly Hills.

While Lohan was wearing an alcohol-detecting anklet at the time of her arrest, it is unclear whether it played a role in her arrest.
