Amanda Bynes is BACK . . . on another psychiatric hold after being detained by police and receiving a medical evaluation.
According to law enforcement sources, Amanda was the one who called Los Angeles P.D. Saturday morning to report a woman in distress . . . which turned out to be herself. (???)
No word on how long they’ll keep her. By law, it can be up to 72 hours, which is three days.
Just two months ago she was released from a mental health facility.
