Police in Brighton, Colo., are looking for two men accused of impersonating police officers and pulling over at least one woman.

According to police, the woman called police to report the incident over the Memorial Day weekend, but said it happened in April. It was unclear why the woman took so long to report the incident.

The woman told police that she was driving on South 4th Avenue in Brighton on the morning on April 7 when she noticed a car behind her flashing its headlights and the driver motioning her to pull over. She said she stopped because the car was white and had spotlights.

The woman said two men dressed in dark blue police uniforms approached her car and asked for her money or they would arrest her. The woman said she refused their request and they got back in their car and drove off.

The woman described one of the men as a Hispanic male in his late 20s and the other man as a black man in his early 20s. Both wore dark blue, long-sleeved police uniforms with official looking shoulder patches, but had no badges, radio or equipment on their belts. The Hispanic man wore a gold ruby ring on his right hand, according to the woman.

The suspect's car was described as white four-door with two spotlights. There were no markings seen on the car.

Last month, Gov. Bill Owens signed a bill into law that toughens the penalty for impersonating a police officer, raising it from a misdemeanor to a class six felony.

Anyone who recognizes the descriptions of suspects or have information that may help identify them is asked to call the Brighton Police Department tip line at (303) 655-2377. Callers may remain anonymous.

Motorists who are suspicious of stopping for unmarked police vehicles can continue to drive to a busy parking lot and stop, police said. They may also call 911 from their cell phone to confirm to officer's authenticity. Motorists should remain locked in their car until the officer's identity can be confirmed, either by the officers' appearance, badge and identification card, or the appearance of a second, fully-marked car.
