WYNNEFIELD HEIGHTS, Pa. -- State Police have launched an investigation into an alleged road-rage incident last month that involved a Camden County sheriff's officer, WPVI 6 reported.

A 25-year-old woman said a driver cut her off Aug. 1 and began driving alongside her on I-95 near the Vine Street Expressway.

The driver, later identified as 37-year-old Brian McDonald, then pulled a gun and pointed it at the woman, she told authorities. She recorded the license plate number which led to a warrant being issued for McDonald on charges of terroristic threats and possession of an instrument of crime. McDonald turned himself in Wednesday.

A county spokesman said McDonald has been suspended.
