The woman was driving in the 4000 block of East Jefferson Street around 1 a.m. Saturday when she was stopped by a black SUV that had red and blue lights on the front fender, according to police.

The impersonator had the woman get in the back of his SUV, where he raped her, police said.

The woman described her attacker as a Hispanic man who is about 25 years old, 6-2 and 250 pounds, with slicked-back black hair, thick eyebrows, a mustache and stubble on his face. He was wearing a black tactical-style uniform with a badge and duty belt.
