A woman accused of dragging a police officer and slamming into several cars while fleeing a traffic stop, prompting a nearly two-mile chase through the streets of Boston on Tuesday afternoon, is facing nearly two dozen criminal charges.

A woman is under police guard at a city hospital after she was arrested in connection with a destructive pursuit that started in downtown Boston and ended in the South End.

Frantic 911 calls rang across the city as a woman in a black SUV barreled through downtown Boston, hitting cars, traffic poles and nearly police. The driver, who has not yet been identified, was arrested Tuesday afternoon after the chaotic chase, during which police say she struck multiple vehicles and dragged an officer.
