A motorist was chased, rear-ended and shot by a group of men early this morning in South Philadelphia, according to police.

The 28-year-old victim told police he was driving when a group of men in a white Pontiac began chasing him and then rear-ended his vehicle at 15th and Webster streets, causing an accident.

The men in the offending car got out of their vehicle and one of the men pulled a gun and fired a single shot through the windshield of the victim's car, police said.

The victim suffered a graze wound to his head and was transported to Thomas Jefferson University Hospital in stable condition.

The suspects fled the scene but their car - with heavy front-end damage - was found on Cleveland Street near Wharton in Point Breeze.

Police said they have several people they are questioning but no charges have been filed yet.
