Pittsburgh Bureau of Police officers from Zone 4 responded to a report of vehicle collision at the intersection of Murray Avenue and Northumberland Street just before 10:45 a.m.

When officers arrived on scene they found a private ambulance (C&S Ambulance Service Inc.), with a patient in transport, that had been rear-ended by another vehicle.

The other vehicle fled the scene.

The patient did not suffer any injuries in the collision and was transferred to a Pittsburgh Bureau of EMS ambulance that had arrived on scene. The patient was then safely transported to a local hospital.

The C&S Ambulance driver and her female passenger were unhurt. They told police they were stopped at a red light when the ambulance was hit from behind. When they got out to assess the damage, the male driver did a three-point turn and fled southbound on Murray Avenue toward Forbes Avenue.

The vehicle is described as a black Toyota sedan with unknown Ohio plates.

Police are investigating.
