Mischa Barton was placed on involuntary psychiatric hold after calling cops to her Hollywood home on Wednesday night, according to reports. The actress was taken to a mystery location by officers who "assisted her with a medical issue", a Los Angeles Police Department spokesperson has confirmed.

Her representative Craig Schneider tells People.com, "Police were involved due to Ms. Barton's celebrity status, to safely transfer her to medical treatment as per doctor's orders. (She's) OK and resting."

Now Access Hollywood is alleging LAPD officers placed Barton under a 5150 hold, reserved for individuals who present a danger to themselves or others, are gravely disabled or suffer from a mental disorder.

Britney Spears was subjected to the same hold after her meltdown back in January 2008.

As a result of Barton's health issue, she has canceled her appearance at the premiere of her new movie Homecoming.

Producer Austin Stark has confirmed Barton will be absent from the red carpet screening in Tinseltown on Thursday, explaining, "There were some medical problems. She's not able to travel, as far as I know."
