PHILADELPHIA (CBS) — Philadelphia police are investigating what’s described as a road-rage incident along the Roosevelt Boulevard early Friday morning.

It happened at about 2:30 a.m. on the Boulevard at Harbison Avenue.

Police say the three women in an SUV tell them it was unprovoked. They say they were at stopped at a light when a car pulled up next to them, and the occupants began yelling at them.

Then they say a man got out of the car, pulled a gun and opened fire, shattering the rear windows of their Honda Pilot.

No one was hurt.

Police say the gunman had dreadlocked hair, and was wearing a gray-hooded sweatshirt. The driver was described as a heavy set woman with curly hair. They were in a gold sedan with tinted windows, possibly a Dodge.

Investigators are hoping to find surveillance video from the area to help identify that vehicle.

So far, no arrests have been made.
