Mischa Barton has been placed under involuntary psychiatric hold, Access Hollywood reports, citing a source.
According to Access, the 23-year-old actress is at Cedars-Sinai Medical Center in Los Angeles.
On Wednesday, Barton called police at 3 p.m. with a health problem, LAPD Officer April Harding confirmed to PEOPLE. “We assisted her with a medical issue and removed her from her home,” says Harding. She adds that no paramedics were involved and no arrests were made, but confidentiality laws prevent her from revealing details about Barton’s condition.
The star’s rep, Craig Schneider, tells PEOPLE that police were only needed to protect the former O.C. star from the media as she was transported to her doctor.
Additional calls to the police, the hospital and Barton’s rep were not immediately returned.
