The Minnesota Department of Corrections is investigating one of its officers after he was recorded taunting a group of Black people peacefully protesting police brutality on Sunday and shouting profanities at them.

Sgt. Paul Gorder, who has worked at Minnesota Correctional Facility – Stillwater for more than 30 years, has been placed on “investigative leave” while MN DOC’s Office of Professional Accountability reviews the matter, a spokeswoman for the department told HuffPost in an email Monday.

“The actions in this video in no way reflect the values of the MN DOC,” the spokeswoman wrote.

In the nearly 40-second video, recorded on a cellphone by one of the protesters, Gorder can be seen giving the middle finger to a small group of demonstrators in Stillwater, Minnesota, about 25 miles east of Minneapolis.

“Fuck you, fuckers!” shouted Gorder, who was donning American flag shorts.
