Amanda Bynes has 72 hours to come to her senses.  The troubled actress has been placed on 5150 psychiatric hold in California after trying to start a fire in the driveway of a Thousand Oaks resident.

Bynes may finally, if not temporarily, get the help she so obviously needs after being involuntarily hospitalized following the alleged disturbance.

According to the Ventura County Sheriff's Office, the 27-year-old actress was arrested after she caused attempted to star a camp fire in the driveway of an elderly woman's home on the 200 block of Avenida De Los Arboles in Thousand Oaks, California Monday night.

"Deputies investigated the incident and determined that she met the criteria of 5150 W&I (California Welfare & Institutions Code). She was detained and taken for a mental health evaluation," the statement concludes.

The 5150 code allows individuals to be placed in protective custody against their will if they're determined to be a danger to themselves or others.  Britney Spears was placed on a 5150 hold in January of 2008 when she had her widely-publicized meltdown.  By law, she can only be held against her will for 72 hours before she's released on her own recognicense.

After the fire department responded, they reportedly found Bynes standing next to the fire, according to ABC News.

Bynes, who has been exhibiting wackadoodle behavior including allegedly attempting to assault fans on the Atlantic City boardwalk, is racking up quite the rap sheet, having been  arrested for reckless endangerment, possession of marijuana and a DUI.  She has been exhibiting irrational behavior at best accusing police of sexual harassment and harassing celebrities on Twitter.

Just this past weekend Bynes was ejected from a New York hotel after berating the staff and smoking pot.
