Mischa Barton was removed from her West Hollywood home Wednesday by police, an LAPD spokesperson confirms to Usmagazine.com.
"We responded to her home last night on a medical issue," Officer April Harding tells Us. "We assisted with it. She was removed from her home."
Harding tells Us no 911 call was received, and that she was not sure if Barton, 23, was in distress. When asked if the actress was cooperative, she tells Us: "I guess." Harding did not release details on where Barton was taken, citing California privacy laws. But Access Hollywood reports Barton was placed under an involuntary psychiatric hold (also known as a 5150) by the Los Angeles Police Department before being transferred to Cedars-Sinai Medical Center. (According to the code, authorities can hold a person involuntarily if they present a danger to themselves or others. This same code was used to hold Britney Spears twice in Los Angeles in January 2008.) In a statement, Barton's rep Craig Schneider tells Us: "Police were involved due to Ms. Barton's celebrity status; to ensure her safe transfer to medical treatment for which she remains hospitalized as per the recommendation of her doctor."
A source tells Us Barton called the police herself after having a "freak out." Barton won't be at the NYC premiere of her new movie, Homecoming, tonight, an event rep tells Us. The actress -- best known for her role on The O.C. -- was charged in 2008 with DUI and marijuana possession. She was sentenced to 36 months probation, told to attend alcohol education classes and pay a fine. Barton checked into rehab after the incident, she said, because "I wanted to prove to the court that I would take it completely seriously.
