Actress Amanda Bynes was placed on an involuntary psychiatric hold by California sheriff’s deputies on Monday night after she set a small fire in a stranger’s driveway.

According to Captain Don Aguilar of the Ventura County Sheriff’s Department, Bynes was “involved in a disturbance in a residential neighborhood last night in Thousand Oaks.” Fire officials responded shortly before 9 p.m. to a report of a gas can on fire in a driveway and after investigating the incident and speaking to Bynes, 27, they determined that she met the criteria for a 5150 psychiatric hold. The homeowners have said that they had no ties to the troubled former child star.

A 5150 order places an individual under a 72-hour involuntary psychiatric hold, during which they are given a mental health evaluation. The order under the section of the California Welfare & Institutions Code allows for the involuntary hold when someone “make[s] statements that they’re either a danger to themselves or others, or gravely disabled.”

The same provision was used in 2008 on Britney Spears when the singer’s erratic behavior sparked concern from family and officials. Aguilar said no medical aid was rendered at the scene and at this time no criminal charges have been made against Bynes.
