Six people are behind bars stemming from an officer-involved car chase from Scituate to Providence.  Police say a 17-year-old girl is accused of breaking into a home.  She allegedly jumped into an SUV with five passengers and side-swiped three cars and rear-ended a pickup truck.  The three-town chase ended on Smith Street after the female driver crashed the car.  Police found six-pounds of pot and a gun inside the SUV.  All six people face a slew of charges, including reckless driving, possession and obstruction of a police officer.  The name of the driver hasn't been released.
