MINNEAPOLIS (WCCO) – Authorities in northwestern Minnesota are asking the public to be on alert following two reports Monday night of a man impersonating a police officer.

The first report was made in Becker County, about 30 miles east of Moorhead. The sheriff’s office says a woman reported being pulled over on County Road 7 near Lake Park by a man driving a white Jeep equipped with blue and white flashing lights.

The woman reported that the man, who appeared between 25 and 30 years old, told her she had a broken tail light. He asked to see her identification and told her to get out of the car.

When the woman noticed he wasn’t wearing a proper uniform, only a black jacket with a radio microphone on the lapel, she asked for his law enforcement credentials. He then walked back to his Jeep and drove off.
