Connecticut police are investigating a possible case of police impersonation after a man pulled a woman over and told her she was beautiful.

The woman was driving on an interstate in the town of South Windsor around 2:30 p.m. on New Year’s Eve when a black Chevy Impala turned on flashing red and blue lights behind the windshield, police said.

The woman stopped and a man approached her car and requested her license and registration.

He asked a few questions, told the woman she was beautiful, then gave her back her papers, returned to his car, then continued to follow her onto Route 5 and Sullivan Avenue, police said.

The woman reported the incident several hours later and police said there is no record of her registration or license being run by a police agency.

The woman described the man as about 5-feet-10, with a medium build. He was wearing dark jeans, a black shirt, a black hooded sweatshirt and had some type of badge on a chain around his neck and a handgun on his hip, police said.

The vehicle had no front license plate or markings.

Anyone with information about this incident should call South Windsor Police at 860-644-2551.

Police advise residents who believe they are being pulled over by someone who might be impersonating a police officer to put on your flashers, drive the speed limit and call 911 from your cell phone.

Tell the 911 dispatcher that you are concerned.

If you do not have a cell phone, drive to a well-lit, busy area, such as the parking lot of a busy store.

Do not stop your vehicle or get out of it until a dispatcher can confirm you are being pulled over by a legitimate police officer.

If the dispatcher cannot confirm that you are being pulled over by a police officer, stay on the line with the dispatcher and drive carefully to a safe place, such as a local police department.

If you cannot dial 911, ask the plainclothes officer to have a uniformed officer in a marked car respond to your location before you surrender documentation, and ask for their photo identification.

Report any suspicious incidents, such as the one above, immediately to the local police agency.
