• Bynes recently missed an "All That" reunion, which included costars Kel Mitchell and Kenan Thompson.

Amanda Bynes was placed on a 72-hour psychiatric hold, TODAY reported, after the actor was discovered wandering the streets of Los Angeles on Sunday.

The "She's the Man" actor, who has bipolar disorder and struggled with substance abuse in the past, flagged down a car and told the driver she was coming down from a psychotic episode, according to TMZ.

She then called 9-1-1 and was transported to a nearby police station where a mental health expert determined the actor should be placed on a 5150 hold, which allows an adult experiencing a mental health crisis and causing danger to themselves or others to be involuntarily detained for a 72-hour psychiatric hospitalization.

Bipolar Disorder is characterized by manic and depressive mood episodes that can last from days to weeks, according to the American Psychiatric Association; Bynes reportedly had not been taking her medication prior to being placed on the psychiatric hold, Bynes' ex-fiance Paul Michael told Page Six.

A representative for the actor didn't immediately respond to Insider's request for comment.

Nearly one year ago, Bynes's eight-year conservatorship under her mother, Lynn, ended after a judge determined the legal arrangement was no longer required. The actor had been placed under a conservatorship in 2013 following several disturbing incidents that included allegedly setting fire to a driveway, according to NPR.

"In the last several years, I have been working hard to improve my health so that I can live and work independently, and I will continue to prioritize my well-being in this next chapter," Bynes said in a statement through her attorney, David Esquibias, in March 2022, adding that she was excited about several upcoming endeavors, including a fragrance line.

The actor was reportedly "doing very well," Esquibias told People magazine at the time, adding that she and Michael were actively searching for furniture. The couple ended their engagement in 2022.

Bynes most recently missed an "All That" reunion panel at the second annual '90s Con in Connecticut on Saturday, according to Us Weekly, which would have marked her first public appearance since the conservatorship ended. Former costar Kel Mitchell encouraged the audience to "send a prayer" to Bynes for her to feel better.

Mitchell and Kenan Thompson also discussed Bynes during an interview with "Entertainment Tonight" at the event.

"I've just been praying for her," Mitchell said. "We're just continuing to pray for her on her journey, and it's answered prayers that she's doing a lot better."
