Just short of two weeks after she began making headlines for alarming behaviors again, former child star Amanda Bynes is back in a treatment facility and under a new psychiatric hold.

Amanda Bynes Claims To Be Engaged

According to Entertainment Weekly, Bynes was admitted to a rehab facility shortly after arriving at LAX airport on Friday afternoon, and she has once again been put on a 5150 psychiatric hold, which will last a minimum of 72 hours, but could extend up to two weeks. Her parents are reportedly seeking to become her conservators once again.

Bynes was previously placed on a 5150 psychiatric hold in July 2013 after increasingly alarming behavior throughout 2012 and 2013. She stayed in a rehab facility, reportedly fighting addiction to marijuana and mental health disorders including schizophrenia and bipolar. She was released into the first conservatorship with her parents in December, but began to act erratically again after it ended in August.

Amanda Bynes Resurfaces On Twitter

The most recent saga began September 28 when she was arrested for a DUI in California, and not long after, reports surfaced that she had been kicked out of the Fashion Institute of Design and Merchandising. She then headed to New York where she was seen exhibiting an array of strange behaviors around the city, and was caught shoplifting twice in the same day.

Her strange behaviors also began emerging once again on Twitter, with the former actress once again going off on rants, this time against the media and her family. In fact, she even tweeted alarming allegations against her father on Friday, claiming he physically and verbally abused her as a child (the tweets have since been deleted).

She also claimed he had a microchip implanted in her brain.

Before she was taken back into custody in Los Angeles, Bynes' siblings, Jillian O'Keefe and Tommy Bynes, reportedly spoke out against her allegations, sticking up for their father and saying it hurt them that Amanda was saying awful things about him.

"We are disturbed beyond words that Amanda would come up with such a fabrication as a way to avoid getting much needed help or treatment. [They are] the most wonderful parents who have ever lived. We are pained by [Amanda's] behavior but we absolutely give our full unconditional love and support to our wonderful parents," they said through a statement by their lawyer.
