Mischa Barton On Psychiatric Hold

The OC star Mischa Barton was held under Section 5150 involuntary psychiatric ward at Cedars-Sinai Medical Center in Los Angeles.

Under 5150, a person can be held involuntarily in the psychiatric ward when they present a danger to themselves or others, or suffer from a mental disorder.

Police reported that the 23-year old actress called to ask assistance for a "health problem." LAPD Officer April Harding said there were no paramedics involved and they "assisted her with a medical issue and removed her from her home."

Mischa Barton's 5150 psychiatric ward was the same place that Britney Spears went into twice in 2008.
