Amanda Bynes Hospitalized on Psych Hold for Setting Fire

Amanda Bynes's tumultuous off-screen life has taken another sad turn, as the onetime child star has been hospitalized for psychiatric evaluation after allegedly setting a fire in a Los Angeles suburb.

The Ventura County Sheriff's Department confirmed to omg! that Bynes "was involved in a disturbance at a residential area" about an hour outside L.A.

"Deputies responded and held her on 5150 welfare and institutions code [involuntary psychiatric hold] and [Amanda] has been taken for mental evaluation," said Capt. Don Aguilar.

A psychiatric hold can last up to 72 hours. (Britney Spears was infamously put under one in January 2008.)

The Ventura County Fire Department responded to a 911 call at 8:38 p.m. on Monday, and Bynes was taken into custody after she was accused of starting a blaze in the driveway of an elderly woman. No immediate word on what prompted her alleged arson and as of now, no charges have been filed against the actress.

According to reports, the 27-year-old actress — who has been unusually silent on Twitter since Friday — has caused a few disturbances while in the Los Angeles area since arriving on the West Coast over weekend.

On Sunday, Bynes returned to her hometown of Thousand Oaks, California, where she was accused of trespassing at a retirement center. The "Easy A" actress allegedly claimed she was trying to visit a relative but was turned away by management due to her bizarre behavior. When she returned later cops were called although she was not arrested.

This isn't the first time Bynes has undergone psychiatric evaluation. On May 23, Amanda was arrested for allegedly throwing a bong out of the window of her 36th floor apartment in NYC. She was taken to Roosevelt Hospital to undergo a psychiatric evaluation before a Midtown police station to be processed.

Before leaving New York last week, Bynes was reportedly booted from the Ritz-Carlton after some allegedly unruly behavior.

The former Nickelodeon star is due in a New York court on August 26 to face charges of reckless endangerment, tampering with evidence and marijuana possession stemming from her May arrest.
