Amanda Bynes' psychiatric hold extended two more weeks

Amanda Bynes' stay at a California treatment facility has been extended, it was reported Monday.

According to E! News, the actress will now remain at the facility for two more weeks.

Tamar Arminak, the attorney representing Bynes' family, confirmed to Reuters on Friday that the 28-year-old was placed under an involuntary psychiatric hold after flying from New York to Los Angeles.

That development came after Bynes began displaying erratic behavior in recent weeks, including a DUI arrest, bizarre Twitter rants and accusing her father of sexual abuse -- claims she later retracted and blamed on a "microchip" in her head.

"My dad never did any of those things. The microchip in my brain made me say those things but he's the one that ordered them to microchip me," she tweeted.

The former child star, who pleaded no contest to alcohol-related reckless driving in February and was sentenced to three years of probation, displayed similar troubling behavior last year, which culminated in her receiving psychiatric treatment after police say she set a small fire in a driveway of a Los Angeles-area home.
