A Baltimore police officer was injured Sunday evening when his speeding patrol car, its siren blaring and its emergency lights flashing, crashed into a pickup truck on York Road in North Baltimore and flipped it onto its roof. Officers who went to the scene of the accident said it appeared to have occurred when the Ford pickup pulled out of a parking lot at 5438 York Road in front of the officer's white-and-blue Chevrolet Impala. The officer, who was not immediately identified, was taken to Maryland Shock Trauma Center, possibly with a broken ankle or leg. Debris from both vehicles littered the road. After hitting the truck, the police car hit a red Mercury Tracer and then smashed into the brick facade of a Subway restaurant, demolishing some of the bricks and shattering two plate-glass windows. The front of the car was wrecked, its air bags deployed.
