A Detroit police officer is under investigation after he filmed himself making racist remarks about a young Black woman he forced to walk home in dangerously freezing temperatures after a traffic stop earlier this week.

Officer Gary Steele posted video to social media site Snapchat on Tuesday, taunting the woman after calling for her car to be towed. leaving her to walk herself home. Video obtained by station WXYZ Detroit showed the young woman’s car stopped on the side of a snowy roadway as she wanders alone in the dark.

Steele reportedly pulled the woman over for driving with expired license plate tags.

At the time, temperatures were below freezing, as the city found itself in the midst of a polar vortex impacting much of the U.S. Midwest. At least 21 deaths are believed to be related to the bitter weather system, The New York Times reported.

In the video, Steele is heard making snide remarks about the woman, identified as Ariel Moore, as she walks from the scene.

“Walk of shame, in the cold, priceless,” a person in the video says, using the “Celebrate Black History Month” filter and the caption “What Black Girl Magic Looks Like.”

The officer then signs off with a “Bye, Felicia!” to end the clip.

Moore’s mother, Monique Mobley, expressed outrage after watching the video.

“What they put on there, that’s racist,” Mobley told WXYZ. “They demeaned by child for no reason.”
