UPDATE: Mischa Barton In Involuntary Psychiatric Hold!

UPDATE: MSNBC is reporting that Mischa Barton was placed under an involuntary psychiatric hold (also known as a 5150) by the Los Angeles Police Department and transferred to Cedars-Sinai Medical Center on Wednesday evening.

As we all remember, this is the same 5150 that Britney Spears was placed under on that fateful night back in January 2008!

We’ll keep you updated.

Mischa Barton didn’t have a very good Wednesday.

Us Magazine reports that the 23-year-old former O.C. actress was removed from her home in West Hollywood yesterday afternoon by Los Angeles Police Department officers, after she put in a non-911 call to the LAPD.

“We responded to her home last night on a medical issue,” Officer April Harding tells the magazine. “We assisted with it. She was removed from her home.”

Asked if Barton had been cooperative with police, Harding replied, “I guess.”

Harding did not reveal where the actress was taken after being removed from her home.

Accounts of the incident seem to differ. While Us quotes a source saying that Barton called the police after having a “freak out,” Web site RPulse, which claims to have spoken with a Barton family representative, says that Mischa was taken to the hospital after suffering complications from oral surgery. (Barton recently had her wisdom teeth removed.)

According to the site, Barton is recovering with her family and is being treated with antibiotics.
