Police are on the lookout for a man who may be impersonating one of their own.

A woman was traveling on Newberg Road in Wilson, Northampton Co., around 8:30 p.m. Thursday when she swerved to avoid crashing into a oncoming pickup truck, police said.

The woman said the truck began following her, and at times, the driver switched on a blue light.

Wilson police said they believe the man was impersonating an officer and was trying to stop the woman, who eventually got the truck off her tail in the area of 19th and Ferry streets.
