Actress under psychiatric lockdown for at least two weeks

Amanda Bynes will be kept on psychiatric hold for two more weeks, it has been revealed.

The actress was taken to Las Encinas hospital in Los Angeles last Friday, immediately after she touched down at LAX airport from New York. It's believed she thought she was being taken to a hotel but that her parents had arranged for her to be taken directly into medical care.

Just hours before being admitted to the treatment facility last week, Amanda took to Twitter to post a series of shocking allegations about her father, claiming he had verbally and physically abused her as a child and had "fondled himself" in front of her many times.

She then deleted the tweets and admitted her father had never done any of those things, but that a microchip in her brain was the cause of her confusion:

The actress' parents are said to be relieved that she will receive the treatment she needs. "They're happy she's safe and that Amanda is finally getting some help," said a source.

The star is being held under section 5150 of the California Welfare and Institutions Code, which allows for mentally ill people who are a danger to themselves or others to be taken into care against their will.
