A pedestrian and a motorcycle driver were injured in Park Slope last night after the motorcycle driver collided with the pedestrian.

Police say that they responded to a 911 call at about 4:55 p.m. about a traffic incident at Flatbush Avenue and Sterling Street on Friday night. A preliminary investigation revealed that the pedestrian, a 44-year-old woman, was crossing east to west on Sterling Street when she walked between two buses. When she emerged from between the buses, she was struck by the 28-year-old motorcycle driver. The motorcyclist was thrown from his vehicle, which continued to skid until it hit a city bus.

Both the driver and the pedestrian were transported to Methodist Hospital. The pedestrian remains in critical condition with head trauma while the driver had a broken left hand and bruising to his body, but was in otherwise stable condition.

Police say the collision is under investigation by the Crash Investigation Squad and that at the moment no arrests have been made.
