Authorities are investigating an incident involving a possible police impersonator in Mount Gretna.
Cornwall police said the man identified himself as "PA State Police" when he approached a contractor working on a Boehm Avenue home this morning.
The unknown man wanted to know what the contractor was doing and attempted to go into the home, and when he was told he was not permitted inside the residence he waited in his car until the contractor came outside, police said.
He then told the contractor to "leave," police said.
The man was described as white, 6'0" tall, 240 lbs, clean shaven, with light brown hair with a buzz cut. He was wearing dark blue pants and a lighter blue polo shirt that did not have any badge or insignia, police said.
He was driving a blue, older model full-size Chevrolet Caprice with a spotlight on the driver's post and unknown color light bar on the rear deck.
There were no police insignias on the car, which had a regular Pennsylvania license plate, police said.
