(UPI) - Rioters in Los Angeles react to another fake Toyota 911 caller by overturning the car and setting it ablaze. The driver, an 89-year old woman, phoned 911 claiming that her Prius accelerated without her pressing the gas. 911 officials quickly triangulated her position to a stoplight in the southeast part of town. Officers converged upon the woman while the 911 operator held her on the phone. The only thing discovered stuck in the ON position was her left turn signal. Passersby overwhelmed her vehicle after the call was intercepted via police scanner and posted on youtube.
